I have been playing Halo for years, and this one consistently since it has came out, i would like to know why i am getting banned? especially when I leave a game where it puts me in a team of 3 against a team of 4, which i am obviously not going to take as it will effect my rank. Please fix this.
As said above, there is an official ban thread pinned in the support forum. You should use that thread for all questions and discussions about being banned.
