I was thinking, when you play a match in multiplayer your team is a certain colour and they (if left to default) have markers above their head, well why not just get rid of the team colour and just have the green marker, that way you can tell your team apart from enemies and you get to play in your prefered colour. It wouldn't make a massive difference.

Yeah but there are enough idiots out there who do that even if you are the same colour and you have a massive green marker above your head.
