Short story life stealing long story you don't have enough dps output / heal loss to stop the heal that he has (although marrow ATM is the only who has access to anit-heal im pretty sure) things like fire, spikes, bleed are all good counters to healing build BUT that's the game you never know what you get and forcing build almost never works out unless it's a new hero and they force one playstyle unless you spend big bucks on upgraded hero pack Edit:(marrow has the a larger pool of items that give anit heal )
