[Jack T]

Im confused, i do ranking matches on team doubles, i win a game with a good k/d score but i don't go up a level, for example:
me and my friend played a match i had the oddball for 60 seconds he had 40, we both had 7 kills and 2 deaths, he goes up and i stay the same??? am i banned from getting level or is something wrong here?
advice would be helpfull here xD

Dont wory about it. You will go up eventually. I won 3 games in a row on Lone Wolf and didnt go up. it happens!
