I hate to bring this up, but it would be most helpful for Htc to take some of the good designs of AW (one of the few) into their whole map interface.
Briefing rooms, where you can see quickly who is there and chat with them while you wait (this already exists, but is not as simple and intuitive).
This would also be great for towers, so you can privately chat with those upping from the same base without doing it across the text buffer for other channels.
These briefing rooms would greatly help missions. Having your CO tell you exactly what is expected, and other good instructions, not being broadcast to the normal text buffer would be nice. Makes it feel like you are actually in a briefing, and builds a tighter more realistic mission.
Map is just funky. Maybe just show important alt changes with it and get rid of the silly shadding and stuff. While they are at it, get rid of the bar dar and do something more quantitative.
