The main problem with havoc in pvp right now is that it has almost no survivability, which is necessary for a melee class to compete especially in this burst meta. It’s actually mind-boggling when you compare what DH gets compared to sub rogue for defensives.
DH: Blur: dodge +50% and reduced dmg taken by 20%, 1 minute cooldown
Besides that there’s Darkness which is useless in pvp and on a 3 minute cooldown. You could have both of these active and still die in seconds.
Meanwhile rogue’s feint ability outclasses all of our defensives combined, and that’s just one ability. With the talent it’s a 30% reduction on ST dmg taken and 40% reduction on AOE dmg taken, on a 15 second cooldown!!! Besides that they get stealth, vanish, a self-heal on 30 sec cd, 100% dodge and 100% magic immunity both on 2 min cd, 2 baseline stuns, and blind.
It’s insane how screwed over DH is right now. You feel like a sitting duck in pvp, everyone targets you first because they know you have no defensives.
