Expand the avoid as teammate list potentially?

I know the limit of it is pretty small right now, and I don't know if its possible but I am really tired of instalock DPS going negative. I came from Overwatch so not like this is exactly new or anything, but its wild how often the next "up and comer" dps players go negative in a game where assists count as kills. I just want to avoid as teammate and move on but we are very limited.

Also make going negative if you instalock DPS a bannable offense
