PvP is about being better then the other team, If you're facing a pally... you watch out for when he pops wings + goak... and CC/Dispel to compleatly block his burst, if you don't and he trains you.... expect to get wrecked without any CD's up.
Same thing happened, warrior was ignored when he had his buff going, no CC was applied and i didn't see any CD popped by the shaman.
If you're going to nerf one class due to their RANDOM burst they can have, then nerf the controlled burst the pallies have. Both can be seen, both can be CCed to avoided.
