Post game scoreboard, and account stats.

The ability to be able to review each game and how well each player performed during that game as well as the ability to go to your own profile and see your accounts stats across lifetime and seasons. (preferable including months and years) as well as a graph of how the player has performed in the game, including KD, KDA, Kills through portals, and games won.

An option to have your personal stats on your profile to be available for other players to see or not would also be fantastic.
