when it comes to dmg true, but seeing how that priest is specced, im guessing hes having way more lasting power than other spriest and hes like... basically a mana battery, which is what his guild probably need him as so.

Well he does provide an awesome of mana. Everyone just wants to be with him.

you have no mana bar

You know what i mean.

i think your gay lololololol

Lasting power is fine without mental agility. It's all about potting, timing shadowfiend. Extra bonus if you get a shaman in group or a sensible feral druid.

A shadowpriest's true function is to provide mana regen to the group. That does not happen if the dmg output from the priest is lacking. Call me a perfectionist, or whatever, that's just my 2 cents as I have been making sure priests in my guild were optimally specced for raids. At least that way, we have one less thing to blame if things dont go out well during an attempt.

when it comes to hardcore WoW, everyone's pretty much a perfectionist, so no harm in that.

its true that you dont really need mental agi for lasting power (as the majority if spriests dont have it anyways) but it prolly helps on situations like kurei explained, where theres rarely med times between pulls, or lollongfights like illidan and his lol phases that avg's like 15-25min fight? (correct me if im wrong).

its kinda like, if you need to pot with out agi, with it you prolly can save that pot. or you'll be the one thats still casting, while the other spriest is oom even after both spriests potted kinda deal.
dmg output wise shouldnt be all too drastic compared both spriests as you arent losing the core talents of shadow. pretty much just mindblast and its crit, and its on a cooldown regardless.

Yup, Illidan's fight is around 20ish minutes long, just as long as Kael's, but more intensive dpsing. And with our WWS it could be calculated that mental agility will save prolly around 3k-ish mana over the length of that, hardly something worth that much seeing that mana coming back from VT would be more than 30k mana return. With perma potting, and as said correctly timed shadowfiend, there is almost no need for slacking dpsing except for one: Alar P1 where there is no threat issue and you go full rotation dps including SW:D for 6mins, then again, I didnt have a shaman in my group there. For continuous fights, we do that too during our trash clearance of instance and we hardly pause for breaks and I didnt see the need coz all i had to do was pop out of combat for 10secs and drink up.

A full dps rotation set with at least 4imp MB talent would drastically increase dps, and it could push your mindblast + VT total dmg from a boss encounter to around 50%ish dmg. In PvE burst damage is quite important too and losing a lil out of imp mb would slightly hinder that.

Anyways, I'm not turning this into a shadowpriest raiding thread, sorry OP for detouring a lil. Wont happen on my part again in this thread

this forum is infamous for thread derailing anyways, and no harm in having solid constructive discussions going on, at least imo.

hell, i dont see how this discussion is too far away from ZA too as theres prolly spriests runnin ZA

judgement of wisdom.

you still dont have a mana bar.
