[quote][b]Posted by:[/b] Twis777 Pretty much you have an EXP bar and you need like 2-4 wins on any level to rank up. Once you win your EXP bar goes up, when you lose your EXP bar goes down. If you lose a lot then you will go down a lot. It is a lot better than the Halo 3 ranking system and more predictable.[/quote] not true at low ranks (1-15 or so) it can take 1-2 games to rank up at 16 - 20 about 2-3 games 21-40 3-5+ games depending on rank 41 - 46 4+ games depending on rank 47-50 can take 4 games, or it can take a lot like 15 straight games (took me 29 straight wins to go from 45 - 50 (legit)) and 1 lost can equal 4 - 6 wins so it's almost impossible to get to a 50 legit without a constant win streak
