This may have been discussed but I think if team damage percentages were added in its own grid next to the players name, it would actively help players to watch their attacks and teach them not to be spammy or dive mad on 2 teammates attacking 1 person.
It would be a positive type of public shame, because more players would be alert of a person’s team damage as well as the person himself/herself to think, “hey I’m doing something wrong here and need to improve my approach.”
I wonder if anyone would be up for something like that.
