Now that the patch is live, we know which changes made it and which were cut in development. Vitality's buff was cut in half, but combat rogues are still sitting quite pretty. Assassination had a last-minute 10% boost to its damage via Assassin's Resolve, which should ensure that the spec performs well. Subtlety's Sanguinary Vein buff also stayed put, which should increase the number of subtlety rogues raiding in this tier.
Along with the purely numerical changes, we also have to factor in our new set bonuses, talents, and ability changes that arrived with the patch. Rogues received more changes than usual in this patch cycle, and I am hopeful that we'll continue to excel in PvE while also gaining ground in PvP representation. Patch 5.2 is full of cool new tools for rogues, which has me very excited for this raid tier.
