What is this for? Can I link my members gamertags to xbox somehow?
There aren't any connections to an Xbox gamertag, but I know you can link up tags from certain games like BF4, and sport that on your profile.
From what I can tell - through the use of match reports - you can report a matchup with all the necessary details about the games therein, and this includes the two teams - one being the "home" team, and the other being the "opponent" team, and also deciding which was the winner, which I'm guessing is the specific factor to changing the wins and losses. Actually, when you do the match report, you get to choose which members you want(or were suppose to be) on each team, and choosing win or loss will affect each individual member's win/loss stats.
