Guess what, your explanation didn't make sense buddy. I have proved several things you stated about the system to be wrong. Bungie cannot possibly use any of the formulas you explained. First of all, it takes you much longer to rank up 25-50 than it does 1-25. Also, I played doubles with someone when I first got the game that was much better than me. We won something like 12 or 15 games in a row but he always had much better stats than me and got MVP every single time. When we started, he was a 21 and I was a 15. After we finished I was at 19 and he was 38. Please expain to me how something like that can happen if ranking doesn't take in game stats into account?
