Let's be honest, the neutral colours are the best looking ones and most numerous in the game, but how often do we get to see them? Only in duel. In 4v4 modes it's easy enough to identify an enemy without looking at their colours, so I feel that the neutral colours are under used and under appreciated. They should be available to be used in any game mode, or at least make more available in either attacker or defender. Thoughts?
If they want to give us way to identify friend or foe by looking at their colors then at least they could add option to toggle of this behavior. So if I don't care about that I'd turn it off and see the neutral colors all the time. This could be even extended to multiple options so neutral colors in: 1v1, only on you, only your team, both teams. This way I would decide what I want to see and would not force others to see the same.
