Deathmatch is where people go to practice their aim, and pick their fights. I think players should have a lot more data available to them, to judge how well they're doing. Right now, the only data available to your is your KDA total, and splitup among each enemy. A lot more can be done.

I think it would be useful to include average kills per death, average damage per death, %heads body and leg shots. maybe graph each parameter with time, to see how consistent you've been. constant slope = very consistent, jagged slope = inconsistent.

Sort the scoreboard in different ways: order of kills, order of deaths, order of assists, order by weapon used (by you and enemy) to see which guns you're weakest with and which ones you're weakest against. It could help you identify your weak-points, and improve them (or play to avoid them)

filter out N-way battles, where multiple people get into a joint gunfight. Could help identify how you are handling these situations in hindsight, giving you an opportunity to come up with better ways to counter it. If you're constantly getting shot from multiple directions, this data could teach you to isolate angles better.
