The rank system is broken

I tried to play with some Diamond and Onyx players to get experience against better players. We ended up losing a lot of the matches and I went from a Gold 5 to a Gold 3 with only like 10 losses. I should not lose that much against higher tier players. Not to mention, without a squad it requires luck to get to a higher league unless you can steamroll since people never communicate. Seriously, fix your system.
