Can the AI tell what you're about to do?

I've been noticing some weird AI behavior on my mesmer (lady spaff), boss's and other enemies not casting spells when i have my mouse cursor hovering above an interupt...some boses just don't cast for the entire duration of the battle like they have no spells if I keep it hovering...but they do cast when i change target...using hotkeys negates this of course :P

perhaps other people have experianced this 'AI telepathy' thing, or i'm just imagining it O_o

I've not really noticed it. I just recently made a mesmer so I've been playing her a lot. Playing a Dom mesmer means that I have a few interrupts on my bar and when I have my mouse hovering I haven't noticed any change.

It's probably just me being a mentalist

I sometimes throw SS on things, only to watch them suddenly become statues. Also, when on my ranger, they always cast the spells AFTER I accidentally fire off my interupt.

They know as soon as you cast something though.

Since makes their Interupts PWN FACE because they dont have the Human Reaction Time in the way - with is why you see them interupting your 1/4 sec cast with 1/2 sec interupts..They used their interupt as soon as you hit the spell icon.

Yeah, godly interrupts going on.

I noticed the SS thing too. My lvl 12 SS necro would cast it on graspin ghouls.. they just freeze up.

This type of AI behavior has been going on for a while. I have seen enemy casters do nothing while my mesmer has them targeted (even monks). On the flip side I have seen enemy mesmers, wanding other targets but still interrupt me (wish I could see someone I don't have targeted about to cast a spell, be able to switch target, and interrupt a 1 second cast)

I suppose the AI needs a few tricks to keep them challenging but I wish they would increase the challenge without resorting to cheap AI tactics. Better (or changing) skill sets would be a better choice rather than allowing the AI to cheat in certain instances.

I just tested this.

On my monk, I ran out into The Black Curtain. The mob infront of the warp to ToA started spell spamming me. I died pretty fast.

Ok, I went out a second time, and used Spell Breaker, and noted that they didnt even attempt to use spells.

... O.o

I've had Vengeful weapon inturrupted twice in a row by 2 Exhausting Assaults. =/

I wouldn't be so sure, i can cast anywhere from a 3/4 second to a 1/4 seond spell and be interupted.

Yeah, saw this a lot today with my ellie getting interrupted by dredge. The AI ALSO seems to know what enchantments you have on you. I would guess that the AI is aware of all actions being taken by things hostile to it, and can react to multiple threats however it's most efficient to do so. They literally take in every spell being cast, every swing of a weapon. Then they decide what action to take and take that action, all at speeds no human could ever hope to match. They're still bound by rulkes like recharge and casting times, but their reaction time and awareness of everything can be harsh at times.

I noticed this behavior today, while out skill capping on my ranger. Mouse hovering, and the darned enemy just bashes away, without using the spell I just know it's dying to use. Capped five skills, so I wasn't out there for just a few minutes. Took me hours. (also cause i was chatting)

idk, but AI isnt the best at interupting anyway, i make them cast too late often.. its easy if you watch their wanding motion

That one is easy, attack target 1, tab to target 2, and cast on them Keeps the henchies on target 1, and looks hillarious (my opinion).

You can begin wanding someone and then TAB to another target without stopping your wands on the other. I use this alot in PvP to make 1 caster not use big spells as hes worried about interupts, while interupting another caster if necessary.

I have notice when I was searching for a target for my assassin, every monster that strayed a bit to far, suddenly ran back to the pack when I targettted it. I was just using [tab], to select it. I didn't do anything.
I also have seen monstermobs with aggro circles bigger than the radar screen, after I had attacked them once. They could chase you much further away, once I had attacked them.
Personally I think this kind of behaviour makes the job of mesmer and Assassin les worth, because you're fighting a paranormal AL.

And yet, they just cannot make sister tai heal worth a damn.

Will you join my party? LOL Seriously, though, that is kinda wierd. Ive been wondering about AI reaction times too, especially with interrupts.

I tried the mes interupt thing in the drazach thicket place, they didnt cast when I was hovering on power spike....but...even worse - I pressed enter to open the chat thing to PM my friend to confirm it...and the boss I was targetting start casting...he knew I couldnt activate my skills whilst talking to my friend, it was freaky. I tried it a second time and the same happened.

Yeah, I was thinking about AI telepathy yesterday. I played an interrupt ranger, and frequently when I was waiting for the enemy to make a move, they never did. I had necros go from full health to death without ever casting a spell.
I don't know if they're psychic (or, really, the games prediction routines keep track of your mouse movement AND feeds this information to the mob AI), or if it's just so that mobs sometimes act really stupid and don't cast, and you just notice it more when you're waiting to interrupt.

My vote is for the second.

Oh, I do this all the time. You do a normal attack on someone, then flip around (using the 'target next nearest enemy' button) and check on what the other enemies are doing, or check up on a key enemy - a siege turtle, say - and interrupt them as needed.
You'll keep using your normal attack on the original target until you use an interrupt on another target, only THEN do you switch active target.

It's mainly useful against long casts, like rez signets, meteor showers, and siege turtle attacks.
