I think Bloodwhetting does need to be nerfed in AOE situations, but I don't think they should completely get rid of its AOE capabilities -- getting showered in health is part of WAR's appeal. What they could do is make it so that you only get the heal effect from one GCD, and the cure potency changes depending on if you use a singe target or AOE weapon skill. It could be like 800 potency from a single target weapon skill, and like 100-200 potency using an AOE weapon skill. This way, it remains strong in single target fights, and doesn't scale as extremely as it does currently in AOE situations.
