I don't know what good a tank will do against a good OP, other than taunt and bring another stun. It's not like they don't stomp geared tanks down. I've been destroyed by OP's in about 5-6 seconds as a shield spec. Vanguard, with most of the mid tier pvp gear on ( haven't got the helmet and not quite valor 60 yet ). Their knockdown opener combo's has taken me from full health to less than 25% before I could even get up and then it was vanish only to finish the job seconds later. So in your opinion with OP's it's a game of rock paper scissors but it takes 4 geared rocks to beat your scissor, yes that sounds fair.
