I like to see one tiny thing added to the game, a hunt option. This would allow you to choose a player, and give you a highlight of that person. Their name will be highlighted, on radar, their dot will be blinking/highlighted. When your aircraft points in their direction (12'o clock), a sound will play, I don't know what, I'll leave that to HTC.
A command like .hunt gameid would be ideal. This would allow people to do new stuff, such as when in formation, they can highlight their leader and follow him/her. It could also allow players to have coordinated 1 on 1 in the MA. And obviously, it would allow people to hunt other people.
