I understand the skill system but it's kind of annoying how long it takes to rank up just because you play with a team. I got my 46, then won 6 games on it. Then today I won another one, lost one, won one, lost one, then won another 5... and I'm still a 46! Won 13/lost 2. 7 win streak, then a 5 win streak.. and no rank up.
