I understand Gears Uses a True Skill system which is as impossible to figure out as a clitoris but I have decent stats (at least over a 1.0 K/D), I'm over .500 in most game types and I NEVER quit matches. yet I am still a private. Any insight into that?
Keep playing and keep winning. The ranking system's not based on K/D ratio its based on how many matches you win and whether or not you were favored to win to begin with. Let's say your team wasn't favored to win and you do, it will have more of an affect on your rank. If you keep winning your rank will increase, if you loose then you won't rank up simple as that.
