I'm a protection warrior in pvp myself and i admit that infact we are rather hard to kill but that is the way it should be? I mean if tanks would be squishy we wouldn't have a use in this game.
But there is a downside to all of this for prot warriors, and other tanks aswell. it's the fact that the damage we deal is rather low. We cannot burst the big Jebus out of someone our only strenght over other classes is out survivability. And our moment of glory is when we reach around 30% HP
, but non the less we as prot warriors have a weakness at 30%
. Most of the time at this point every warrior will be popping shieldwall, Laststand and rallying cry combined with Demo shout and that weakness banner thingy
. The key is to disarm (Hex will also help) a warrior right before the point where he does this and pew pew him down. Feral druids have very strong bleeds so just rip, trash (and whatever you kitties have) us and you will do fine
And remember a tank without a shield is a fish in a barrel, just shoot it
