After playing 20 games with her yesterday in one sitting, I’ve reached the point of nausea because most of my teammates still had trouble understanding Whitemane’s limitations. Early levels as with Uther are a complete circus and you’re almost always engaging the enemy at a net loss.
Her mid to late game is fine and my team was often wondering how I was able to heal 90% of missing health in mere seconds during big fights.
Mana returns would probably push her in the wrong direction, but I think she could afford some buffs, even if it’s 5 mana cost per spell (with increased costs on repeat casts during Desperation in mind).
Numbers wise I wasn’t far off from much stronger enemy healers in any of the games and regularly competed with other damage dealers in the game (stat padding, no real kill potential without the talent to root my opponents).
