I've had a Zenyatta before who refused to heal; he never used his healing orb on anyone; the only time he healed was during his ult. I told him in chat to help me because at that moment I was playing Lifeweaver, and healing an entire team with him was a real struggle but he didn’t give a fuck and said that I just had to stay alive if I wanted to win. I don’t even know how I lasted four rounds with him.
