"Pre-nerf" is incorrect. It's pre-buff.

Lately I've been noticing much more interrupts from monster AI and interrupts that should be theoretically impossible. It comes as great frustration when your 1/4 second spells are interrupted by 1/2 second interruption skills.

For example, in Normal Mode, a monster uses Savage Slash which takes 1/2 seconds to activate and Reversal of Fortune takes 1/4 seconds to cast. How is it possible then that the foe manages to interrupt Reversal of Fortune so many times? It defies common mathematics.

It is, therefore, extremely irritating for the poor spellcaster who is subject to these interrupts. It's easy to feel cheated.

Anyone else dislike this?

pre-interrupt.

I've done it on my Mesmer before, I see a target I suspect is very likely to hand out some major smack down, and everything else is recharging, I'll start casting that longer interrupt hoping they will cast something and get it interrupted.

Usually fails, and I remind myself to stop doing that, but sometimes it works.

Nah, its fine with me. This is the one thing that the AI generally does as well or better than ppl. You could always fight fire with fire--heroes and henches with interrupts are just as good. Team up with Erys Vasburg in Factions sometime if you want to see some killer interrupts. But I like the challenge of facing this AI, though admittedly it can be frustrating, especially when there are several of them.

I've been interupted before my castbar hit the screen. Amazing XD

Kinda makes me mad too. I mean, they are consisantly "pre-interupting" with phenominal accuracy.

I think actual pre-interrupting would require inteligence or real AI... mobs don't have that.

It happens to the best of us. I'm mean on the twitcher, but sometimes I twitch and hit power block

[skill=big]Power Block[/skill]

I can catch a Crypt Wraith 1 in 7 times with either [wiki]Concussion Shot[/wiki] or [wiki]Savage Shot[/wiki] on a good day. Otherwise it's a solid 1 out of 10. I've even caught [wiki]Faze Magekiller[/wiki] a few times. It's not foolproof, but it can be done. If able to be done by a human, imagine the computer programmed AI.

There are also a number of interrupts that work as "If target does anything in the next 3 years, you interrupt it and get to lol at them."


And pre-interrupting as a tactic can make sense when facing certain opponents. Its not so much that the AI needs skill to do it, just a skillbar that doesn't give it much choice other than to spam interrupts and hope one of them sticks.

Its not that pre-interrupting tends to be a tactic of thinking, more so a tactic of 'OMG, I have to click my mouse on everything, like now!" which is kind of how the AI does it sometimes...

Sometimes that tactic works by accident. Sometimes it even chains into a series of successful interrupts in the way that if two blind people run around in circles in a room, there is a chance, ever so small, that they will keep smacking into each other over and over again.

Keep in mind there is a major diff between your reaction time and that of the AI, add some lag too.....

What gets me is when a monster is focused on one target, changes to interupt me, then swings back to that target so fast I cant even tell who interupted me!

I swear that monster AI has access to the recharge times of our skills. I found that if I utilize a skill immediately after it recharges, many times I'll get interrupted, even on the 1/4 activation times.

However, if I pause just a second after the recharge timer is up, I can normally get it off.

they don't need to know the recharge time of your skill, they are controlled server side, and your request to use a skill is also handled server side, before you actually get to cast it, so it's not really surprising that they are able to.

also monsters don't try to interrupt, they just plain interrupt, I have never seen a monster cast an interrupt when the target is not using a skill.

Yes...it's called counting. Why shouldn't the AI know? Humans do it too (dshotting BSurge on recharge ftw?)

Technically since a stance has no cast time it shouldn't be able to be interrupted. Yet, I have had on a few occasions a stance get interrupted by the AI. The best example of irony was I had Mantra of Resolve interrupted.

They may occur but I can guarantee that I had Mantra of Resolve interrupted. I was 55ing and using Mantra of Resolve. Next thing I know I was getting interrupted. I looked at the active skills and Mantra of Resolve wasn't up next to the HM icon. I looked down and Mantra of Resolve was recharging. If it wasn't interrupted then the skill must have deactivated itself. With the same area at a different time I had Bonetti's interrupted.

Your stance was removed because you didn't meet the requirements, or something removed it such as wild blow. If you can activate a stance whilst KDed, then obviously, they cannot be interrupted. On the other hand, they CAN be diverted.

The area was the old dead sword farm in Shattered Ravines. There are monks and warriors there. The warriors have and interrupt and don't have Wild Blow. The monks don't have Diversion. anything else I missed?

Mantra of Resolve ends if you can't pay for it. You sure you weren't just e-denied? There are the occasional ranger trolls in the area (forget the name) that have Quicksand.

i dont think its really possible to interupt a stance at all. maybe u just think that the ai interupted it.

From what I've seen of AI interrupts, they are susceptible to fast cast effects. In other words: If you cast a 1/2 sec spell, and get a fc bonus so it only takes 1/4 sec, then the AI will still try to interrupt it (calculating that it can catch the 1/2 sec), but miss because of the fc bonus. I've seen this most often with the Ghostly's Distracting Shot.
Now, if this happened with the spell you cast just before RoF, the savage slash might have been aimed at a previous spell, and missed, but hitting RoF instead.

Alternatively, the AI may class Savage Slash as an attack skill, and therefore spam it randomly, hitting your RoF by pure chance.

This really ticks me off too. doesnt seem like it should be possible. Doesnt happen all too often cause im usually on my warrior or ranger but when it does happen, sometimes I just stare at my screen for a few mins trying to figure out how the hell that just happened. especially if its a skill that casts under a second.
The enemy had to A) realize I was casting a spell. B)change targets. C)Interupt said skill that casts in less than a second. D) switch back to original target it was attacking imediatly.

It MAY be possible with a 3/4 second cast but anything less the odds increase exponetially.

If the enemy AI works like most rangers in AB think now, then most the interupts are just pure luck, since most rangers in AB just wildly spam interupts on recharge, hoping to interupt something. makes me giggle

To be honest, you shouldn't be whining about anything getting interrupted unless it's a stance...which we all know is impossible.

Interrupting is a lot about pre-empting what skills are coming your way. I saw a guy in vD wait, and correctly guess when the flagger was going to cast SoR and dshotted it I believe. It's very possible.

Shiz explains it very nicely. Good interupters in PvP know to guess when somebody is going to cast. Knowing the recharge times of skills (and thus, knowing when they are coming up again) helps a lot.

Good human interrupters would know when and what to interrupt. The AI just tries to interrupt whatever you're casting, wasting an interrupt or seriously dampening your effectiveness.

Quote:
Mantra of Resolve
For 30...78 seconds, you cannot be interrupted, but each time you would have been interrupted, you lose 10...5 Energy or Mantra of Resolve ends.
Whenever those warriors were using Savage Slash, which I think is their interrupt skill, you lost some energy. And when you reach 0 energy, Mantra of Resolve ends. You wouldn't notice cause it'd happen fast and just as fast your Balth Spirit would give you you some energy back from the hit.

There's something really satisfying about doing a twitch interrupt with [skill]power spike[/skill] and managing to catch enemy's [skill]cry of frustration[/skill] in the process.

I D-shoot mending touch, RoF, PS and similar on a regular basis.

Also, try doing the W/Mo or Mo/* trollfarm builds with chained skills. You'll always want to wait one swing in-between casts because the monster will miss your first cast but hit your second.

So if your 1/4 gets interrupted by a 1/2 then it may be because you casted two things in a row.

I think the AI just spams skills and the recharge times and such all seem to coinside with your patern of skills. Like someone said, if you wait a sec or two after your recharge then usually the AI will have already thrown off it's interupts and you won't need to worry.

(I also enjoying timing skills but I hate irratic monks/casters who don't seem to have a patern - so at first I may spam shots in hopes of catching a skill and all the while I start timing, if I time just right I can catch that heal orison or reversal XD Catching reversal is my favorite ^_^!! )

AI interrupts on fast casting skills (like 1/4 and 1/2) most likely occur because they missed the one they wanted to interrupt and hit the next skill.
It's something that happens a lot with rangers.
You have a 1/2 second 'cast' and then a flight time depending on the bow.
If AI uses it on a 1/4 skill, and you cast one right after that, an arrow may hit you while casting.

Furtermore, it could be that the AI reacts on acivation outside skill range.
When this happens, the player moves forward to make a cast and AI can interrupt when the player gets in range.
This is something I used to do a lot with my mesmer and interrupt ranger on AI targets, so it could be a trigger that's also used for AI.

The Summit Defenders in Slavers Exile are a bugger for the target switching thing. They only have one interrupt and there's never more than 2 in a group, usually just the one so the impact on the team is pretty small. One thing they do ALL the time though is they'll be sat there healing something, you'll be out of range then move up and start a nuke on them and they'll instantly switch to you, interrupt you and then go back to healing again. I've got into the habit of drawing out the interrupt with another spell before i cast the one i want.

Well remember, the AI's 1337 interrupting skillz works both ways. Gwen rocks when you load her up with the "Power X" series of interrupts.
