I liked the halo 3 ranking system the only weird thing was that until rank 20 it went fast and you needed to win like 50 games to get there then suddenly torank up 1 leven you needed to win another 50 games (as example not saying this is exactly true). and with the reach ranking system i had more of a feeling of accoplishing something , even when i lose. getting points even when you lose makes the game a bit easier to play for the less good players.
