A Deep-Wounds-like talent that applies to Swipe could fix some our AoE issues, and allowing mastery to scale with said "Deep Wounds" bleed. I can usually top or be near-top on trash pulls, and on fights with heavy target switching, but it's upkeep is very rough at times. Not that I don't enjoy having a difficult rotation, because I do, but we aren't the only ones with AoE troubles. Shadow Priests have pretty much the exact same issue that we do, and Retribution AoE isn't terrific either (although they are addressing that it seems). The problem becomes, I think, allowing something like Swipe to do that, without making it feel too much like Fire Mage / Unholy Death Knight AoE, or for it to feel as powerful.
