To be honest, as long as we still have 1 minute cloak of shadows (and improved sprint and deadly throw will certainly help against mages), casters will never be our biggest threat in arena.  We struggle against heavy armor to get wow gold, and mutilate, even if they actually buffed its damage by 20%, will not be enough against them. Rupture and wound poison help a lot, but I believe the upcoming expose armor change will revolutionize our class about cheap wow gold.

They will not keep 5 stack sunder at 20% armor reduction. I expect something closer to 35% by the time 3.1 goes live, and I fully expect expose armor to be the same way.  With mace spec, serrated blade and full armor penetration gems/enchants/gear, the magic number I am looking for is -65% armor penetrations with expose armor up if I build my character around that stat about World of Warcraft Gold.

That is a lot of sustained damage against heavy armor, and I believe sustained damage will make a much, much bigger difference once they fix burst damage. Coupled with 40% frontal avoidance with base dodge/parry/deflection/lightning reflex, rogue = plate killer? Certainly not out of question. And we should do just fine against casters about cheap wow gold.

Without relentless and lethality, this spec is extremely weak when you do not have cool downs. You also lack any sort of real burst damage other than SS/ghost strike spamming during adrenaline rush to get wow gold. Two adrenaline rush back to back will likely overpower anyone. This has potential to be a great, great arena spec, where cool downs are available every single fight.
