Every "PVP'r" have themselves to blame for they're specific class getting the nerf bat. All I ever see is constant whining about one class or the other till it gets nerfed. Its a vicious cycle that will never end. It will lead to players leaving because of the constant changes to a class/classes that do not necessarily need it. This time all the whining lead to Tankassins getting it. Next patch it will be PT's or Marauder/Sentinels.Then back to square 1 again. The PVP community will never be satisfied and this in turn leads to people not wanting to play the game anymore and move on. When this happens its 1 less person you could've had que up with/against you and pretty soon there will be no one left for you to play.
Just play the game and deal with it. There are plenty of forum posts on how to counter a particular class. Learn it, live it, know it............
Spend more time learning how to beat that other class and less time posting on the forums and you and everybody else will be in a better place, the game as well.
