Not that it will answer your question much, but I made a 5man arena team a couple weeks back. I got steamrolled 0-10 by 2000+ranked teams I never even managed to kill another player. The following week on a Monday I tried to get my 10 matches in. I was ranked 0 and after a 40 min wait w/o getting a match when the queue time said less than a minute for the last 10 players, I gave the whole arena thing the /finger.
