which 3 pve skill is the most useful/best ?

In some situations I prefer evas and in some I prefer PI. Depends on the enemies but both are not my prefered choice when using a discord team. With PI the chance is that the character I put the spell on is dead in seconds before I can even use AP on it.

You could start with AP but I am very carefull for double hexing, I prefer mass hexes like shadow of fear that apply to multiple targets.

I myself like the combination of FH, Necrosis and YMLAD. Necrosis at high rank sunspear is almost at discord damage but much better.

so many choices .. ><

atm i'm using YMLAD, EVAS and Necrosis .

Think about it this way.

Casting Necrosis twice on the same target does 180 damage.

Casting FH on a target once does 180 damage and inflicts Cracked Armor and a healing reduction of 20% on the target (as a result of the Deep Wound).

On the subject of EVAS vs PI, I think you know my position by now . But you can really use EVAS of course, it's personal choice. I've already said that I think EVAS is the better choice in Charr areas. Just play around with both for a while and you'll see which one you like best.

What you said about YMLAD and how it's a bug is true . just tested it .

AP/hex + YMLAD fuels discord . PI while he's down and he should be dead . what about healers tho ? o.o they don't damage . thus pi = no damage .

it's nice having a EVA army lol . I don't have PI atm . but i'll get it soon .

yeah after testing necrosis, i prefer FH . armour ignoring damage is nice but insta cast is nicer . xD

...
Wow.

Let's clarify something. Are you using your build to prime Discord or are you trying to get the most out of Mark of Pain. Both builds will look pretty damn similar but they both have different aims and that aim will affect your choice in PvE skills and your hero setup.

If you want to get the most out of MoP then PI and Necrosis are almost counter productive.

If you're worried about hex removal then cover or fish the removals out with any AoE hex (Reckless Haste, Shadow of Fear, Meekness...).
When using a MoP caller AP goes on the target close to death so it has little chance to expire or be removed.

With Discord it's different. YMLAD+FH+EVAS + the Discord volley will pretty much kill your target. Along with the minions you can push through a lot of the game without too much difficulty.

Evas, ymlad, pi

Or you can just bring a skills that kills anything, including monks.

get pve skills that would fit your build, don't create a build around the pve skills.

everything depends on 'where' and 'what's your goal'. good luck using ymlad or pi at mallyx, good luck starting a fight against a big melee mob with evas.

i usually don't leave the town without pi, while the other pve skills are switchable and circulate all the time, depending on the build i run and location i'm going to. it would be much easier to list completely useless pve skills.

For physicals:
Asuran Scan/EBSoH(or IATS depending on the situation)/IAU

For damage casters:
EBSoH/BUH/PI

For AP casters:
EVAS/FH!/YMLAD or Technobubble

As for profession specific,then SY!,AoHM,SoF and Triple shot are pretty good too.

Dont play healer on pve to know whats better lol.

Like others said,theres no "better pve skills",it all depends on what you're using them for.While some pve skills are pretty useless,would be easier to point those out instead lol.

Is it possible for a build to do both ? Or even more ? Lol . Anyway I like ymlad , evas and fh . The knocklock is very nice esp. Good against monks who are usually the problem . IMO , bosses aren't that scary when you've got barbs and 3 discord spammers .

Mop in disco is mainly there for some 2ndry damage from your minions, if your spike is slow... if you do the spikes right mop has virtually no time to be used, as the target is dead....waste of time.

And if you dont mop your spike target, then none of your hench will target it, again a waste of time. If your lucky the minions will be hit the mop target...but dont bet money on it.

For a mop nuker tho ideally you want some minions and phys to proc mop. NOT disco necs..Disco spikes negate the awesomeness of mop spikes.

And sidenote: barbs+ disco? just to clarify as its quite an ambiguous statment, disco doesnt proc barbs ^^

Yeah . I agree with the part where you said if you do your spikes right, mop has virtually no time to be used, as the target is dead. this has happened many times . however sometimes things don't go your way . like a hex removal from a mes or a sudden heal from a monk .

that's why you bring (at least i do) me (AP nuker with MoP, Barbs, YMLAD, EVAS, FH!), 3 discord necs, 3 physicals and another support / healer .

18 minions from 2 discord necs (according to the builds on pvx), evas and the 3 physicals + barbs = more damage then 3 discord spammer in certain cases .

did i mention earlier ? i prefer EVAS > PI because EVAS allows me to knocklock after i cast AP + YMLAD . also, by the time he's back up standing, 3 discords + some damage here and there would have finished him . rinse and repeat .

PI on the other hand is good . yes, but after trying a few times, PI doesn't seem to work as well against monks . Discord is already armour ignoring . So is the attack skills done by EVAS, YMLAD and FH. These are enough to finish most bosses including eles . more hp bosses e.g. the great destroyer would be an exception xD . anyway, so yeah .. even if i don't use EVAS and just use YMLAD and FH, because i'm a nec, i don't have energy problems . 3 discords + FH is usually enough to kill the targetted foe .

but against monsters like droughtlings that use stoneflesh aura, EVAS = useless .
