shaman screwed... yes and no....
many of have come to terms that we will never be the way it was, far back when wow origonaly started.... shamans have been nerfed since the start of the game... yeah every once and a while we get a small buff, but the way it seemsm now is that when that happens it usually means that the following patch will take something away.
To look at it from a different point of view, we were the class that wasnt broken to begin with, was then fixed for some unknown reason, witch then made it worse.
Now im not telling you to not roll a shaman... by all means do so... my shaman has been my favorite toon i ever started. Great solo wise, great in groups, and decent in pvp, if you know how to play it right...
if you go elemental, youll be a caster with decent abilities a good choice, but easily replaceable.
if you ge enhancement, you will dominate mobs up until outland, and since you have no cc yet, you wont be needed in heroics
if you go restoration, you will be a healling machine, with a low mana pool compared to other healers...
totems are nice, they are getting more survival added to them in wrath... but what they need is some mobility...
roll a shaman and you will have fun i can almost promise you that but most of us are rerolling, because we are tired of having to endure being raped in the ***, with no vasaline, and it seems to have no end in sight...
