Jesus -Yoinking!- Christ, did none of you hear that 343 is currently working on a competitive ranking system? They didn’t release with the game because it wasn’t ready.
READ THIS. PROOF.

It seems like most of you haven’t heard about this because I’ve seen WAY to many threads about this. The bulletin says it will be released some time early next year, so stop begging and just wait for a competitive ranking system.
