An idea for a ranking system in halo 4

Tier based ranking system for all ranked playlists in Halo 4.

Recruit -

Everyone starts in this. You have to win and get a positive +/- in two games in a row to get promoted to the next Tier. You can’t go back to this Tier after promotion.

Tier 1 -

You have to win 50% (10) of your last 20 games to get promoted to the next Tier. You can get promoted after 7 games if you win all of your games.

Tier 2 to 8 -

You have to win 75% (15) of your last 20 games to get promoted to the next Tier. You can get promoted after 7 games if you win all of your games. If you have lost 75% (15) of your last 20 games at any time, you will be demoted.

Tier 9 -

You have to win 75% (75) of your last 100 games to get promoted to the next Tier. You can get promoted after 20 games if you win all of your games. If you have lost 70% (70) of your last 100 games at any time, you will be demoted.

Pro Tier -

You can’t get promoted. If you have lost 70% (70) of your last 100 games at any time, you will be demoted.

Teams and different Tiers:

The Tier of the highest ranked (Player with the highest Tier in the party) will be used to find games. (A party of a Tier 1, 2, 3 and 8 will search a match against other teams of Tier 8).
