Lol what PS are you playing on?nothing will ever break rogues, because they are guaranteed to get an opener that nobody without a healer on his side will be able to survive. Dont state it isnt like this, because everyone who is a little experienced in WoW pvp knows this.
This is broken. solokilling 5 men groups, i felt like a russian cheater. u need like 5 seconds per opponent in open pvp. its so damn broken, and i just dont get it why they dont fix it (by removing stealth, or giving stealth the old -50 % movement and perhaps a -90 % dmg done debuff for the first 8 seconds after breaking stealth). so rogue would be a balanced class, and not a fucking unavoidable oneshotter, that only has to fear a single action from the opponent, that is on a 3 minute cooldown to be able to react to his opener: pvp trinket.
By wasting your cloak to counter a low dmg dot, i dont think anybody will ever be able to help your rogue-play.
