I have 2250 points in 2v2 Bronze. I'm consistently playing against gold, platinum, and diamond, and winning about half. There are 2 people below me by 200 points in my division, who are silver. What do I need to do to move up??? Doesn't make much sense.
Yes the system is annoyingly crappy but just keep winning. You can also try winning 3-5 then intentionally losing 2-3. Ive heard that works for some.
I don't get this part. But as Stag said, patience. Back then I got promoted from rank 40 gold to rank 80 platinum so the system works seemingly randomly. But the emphasis is on seemingly.
