Davio has it at 36. For me I can't get to the 30s because my computer keeps breaking just when I get to the mid 20s >.>
Hehe, yeah. Been 37 a short while, then back to 36 and now even 35.
No matter what I do, I just keep losing some unlucky games, winning some unexpected ones and everything in between. Just very swingy. I can go 4 games without a win and win 4 games in a row just as easy. No matter whether the ranks are 0 or 30+.
I wished they removed the ranking so I didn't have to mind them.
I play vs. unranked/guest players from time to time just to have a different sort of game. A lot of them are even very nice!
