Not 100% sure, but from my trawling forums and looking up
characters in BC, classes that got buffed up are warlocks, pallies
and shamans. Rogues are kinda buffed, but not in totality. Mages
pretty much are ok, but nothing to shout about, unless you are
heavily fire spec, then you can kick some serious ass.
Pallies complaints are the usual, but overall I feel that they are
kinda where they should be. The usual classes that pwn pallies are
still the same - shammies and priests. The rest, any good pally
equally geared should have a fair chance of beating. Not 100% easy,
but a fair chance.
Warlocks are this time are totally hax. I'm not sure what's going
with Bliz's mind. Warlocks can pwn any class with relative ease,
from the looks of it.
Although shamans for some reason complain they are weak. I can't
understand their gripe. I mean, shamans now with dual wield can hit
harder than rogues easily, and they got heals + shocks. From my
point of view, Shamans just got more bad-assed.
The class that got hit by the nerf bat the most are apparently
warriors. The whining by warriors are by far the worse. I can
almost see their reasons, but playing my 60 full fury spec warrior
against 62 mobs did not make me feel any much poorer.
The only deal is, some classes have their 41 point talent kinda
sucky, while sometimes have total pwnz0rship.
