So why take him at all?
Just delete him from the game if he can’t do anything as good as anyone else, his heals are weak(decent for back line healing)
And according to you his utility is absolutely worthless and his ult is pitiful. Mei-be start a campaign to just delete him, why bother keeping a useless hero in the game. He also does not have a CC ability and has no escape so useless in team fights, according to you.
And as far as Ult charging goes I think the flankers have the quickest ult charge, at least in my experience. And anyway I’m comparing abilities
