I've got a few UI suggestions, but rather than wait until I have all the mock-ups assembled I figured I'd present the easiest one right away.
I've noticed that the loading screens display the kills/points needed to win a match, but that this information cannot be found once the match is actually underway, which seems like a minor issue. The fix is simple:
This minor addition would show kills/points required to win the match, and immediately gives teams a sense of how close to victory they are. It's unobtrusive with its darker color scheme, meaning that your current point total is always the first thing that catches your eye, and thus there is little to no chance of the change causing confusion.
Thoughts? Suggestions?
