so, as stated by a blue here -
The thing I am most worried about are the huge number of variables now in terms of who has what ability. It used to be that you knew what cooldowns and escape tools and CC a Frost mage had and you knew what an Arms warrior had to counter them. With the new talent system, you have to be prepared for almost anything. When there are too many variables, you risk losing some of the predictive and reactive tactics that many players (including me) enjoy. If I have no idea what tools you have, I am more likely to just to tunnel on you, blow all my cooldowns, and hope for the best. Not a ton of depth there.

Now, I have to say I dont understand that viewpoint, as an avid pvper (bgs/rbgs/world.) I am looking forward to that very thing. the randomness. If i get charged by an arms warrior.. I have no idea.. can he charge again. will it stun/knock me down? etc etc.. you get the idea. you will not know if that hunter is going to web you when he disengages. or if he can do it more often...until he does it.
I personally, after 7 odd years of playing, am absolutely looking forward to that, to stop thinking along that path..
I garrote him.. when thats done ill kidney, he will iceblock. i get ready to gouge etc.. I like the randomness that goes with it, that you almost have to wait and see what they throw at you before you can react accordingly, I think itll add alot more depth to pvp myself.
