PVP has undegone massive changes form each expansion, there is lots of abilities i could name that were balanced in previous expansions but broken in a game like wod, an 8 sec stun has no place in wod pvp.
And what do you mean "get into that situation" it requires no set up by the rogue and is on a short cd, your going to get hit by multiple 8 sec ks in an average game and we dont all have the luxury to play with ret palas to survive them.
