Win rounds: potential to rank up
Lose rounds: potential to rank down\
EDIT: I was just losing a game against some clan with randoms. it 12 vs. 2 and we made a comeback and won 12 rounds in a row and ended up tying the game. The clan ended up being a buch of 13 year olds yelling "get shat on" and "OH forget MAN WE REKKT YOU #REKT" and it was just the highlight of my day.
I can rest peacefully now.
