This is a spec if you have mute gear but wish to try something different
Talent Calculator - World of Warcraft
I use this and I absolutely destroy everything in BGS, duels, and some arenas. ofc my partner is a warlock or shadow priest so the high damage kinda goes with the comp, but anyway.
HaT, honor among thieves, Is basically a better version of seal fate, except not just yours, but your partners crits add combo points as well. Not only this, it procs off rupture crits. You will also notice I have taken alot of bleed talents and glyphs, this is because with this build, you stack bleeds and I use deadly poison, you dont need to hit the target much to keep high damage rolling. I usually Love shadowstep for mage blinks right into a backstab for 5k!
Also with this build you got a 30% crit increase with backstab and 50% with ambush.
i have 40% already, making this 70 and 90%, very potent. You drive a ****load of combo points up and energy pooling is amazing. Heres what I usually do vs clothys.
Premed, ambush, rupture or kidney, if its a mage sometimes either rupture or wait for a blink, then shadowstep kidney his lame ass and hit backstab a few times. Done.
Sub is underrated it needs to come back, it truly is a good spec when the 100 dmg from hemo isnt mitigated, thats a 100+ dmg.
Theres just so many good talents. I mean in a disc priest/rogue mirror i did for like 10 games, cheat death saved me and my bleeds ran the other rogue down alot while i was stunned. vanish after cheat death gets ya a life saving heal. + all your survivability. rogue vs rogue is so much easier.
