well, because zdaemon and now skulltag too, support custom colors and names for teams, it is not suitable to use team colors for text - it can be invisible on background. but i think you exaggerate this problem - imho teams remain quite distinguishable
great release, unfortunatelly in CTF, it's much harder to tell now what team the respective players are on, looking at the player list it looks like one big FFA, i liked the previous CTF player list better
