To add to that I wouldn't mind a way to set friend/foe colors (as an override to the game set team colors). It's a pain to be on the yellow team 3 times and then all of a sudden on the blue team.

The green and magenta color scheme really doesn't work in the forest levels. The green glowing circle on green grass is over powered by purple/dark armor with a glowing purple weapon, making it hard to tell teams sometime.
