I understand wanting to be able to show off the new skins but please at least make a ranked play just Red vs Blue. There have been too many times where I have accidentally thrown a grenade or shot at a teammate. As well, just blatantly running by an enemy because I couldn’t tell they weren’t on my team. For social playlists and big teams, I don’t care. But for competitive ranked play, the teams need to be more clear. If you don’t want to make it a blanket change for everyone, then maybe just put a setting in so that everyone can personally make it custom skins or B VS R. Everyone can have a choice. If you still want to show off your skins it can be at the screen where they introduce your teammates.
try using brighter or darker enemy outlines, I use blue for teammates and yellow for enemies.

Lol, 11 months later…
Odds are they’ve moved on by now.
