Rogues have many issues right now so some buffs are needed. You can tell based on loot in dungeons raids and even the rare boa items or holiday event stuff Blizzard really wants ppl to play rogues and the player base just doesn't seem to want to. Hell after saying they would never give one spec or class its own legendary for years they gave rogues dagers in DS that were one of the easiest ones to get. As soon as that bribe benefit was a thing of the past the rogue numbers dropped like a rock.
