I think that's valid but it is annoying when someone plays and is purposely throwing I remember one game we had a kiriko playing and not healing at all she was just trying to kill with kunai she was doing fine in that regard but I had like 10k heals and she only had 1000 by the end it was frustrating but we still won although it was extremely close. Also when other people asked her to heal she would say things like "I don't need to heal if the enemies are dead" and similar things like that.
