Some people refuse to use team chat and talk about things that are team specific and confuse the people on the other team. I suggest that player names in chat should be color coded so that you can easily tell who is on what team without having to look at the scoreboard, like what Team Fortress did. In addition, the commander should have something different about his/her chat text, so that their team knows its the commander and they should probably listen to him/her (make it bold or something).
And the commander should have bind saying "U MOTHERFUCKING NOOB FOLLOW ORDERS AND DONT GET FUCKING KILLED"
Commanders should be able to slap players for say, 10 damage, but have limited slaps, say, one per 3 or 5 minutes.
I think a different colours for comm would be a lot better than Caps, cause I'M A N00B AND I CAN TALK IN CAPS. And Beerdude, you make me lol
