Being affliction, I generally don't stand up long enough to get through the stunlock. I could spec SL/SL but that takes away the fun for me. I have accepted my fate. Each class seems to have it's bane and for the majority of locks, the rogue seems to be just that.
At lower levels, they are generally cake but damn those 70s...
I am looking forward to the expansion more so to see if Blizz actually listened to the suggestions we made as a community on their class feedback thread.

That being said, balanced PvP would only be achieved if there were only 1 class and 1 spec. Blizz never intended true 1v1 balance anyway. If each team in a BG has a decent mix of players, balance is a given and team coordination and players playing their roles truely dictates the outcome. I, for one, am happy with that. The fact that we are grinding machines is a bonus and is where the "OP" tag would be more appropriate for locks.
