If you care more about what your teammates are doing rather than you winning, STOP PLAYING RANKED !
If you'd rather lose the game rather than let a teammate that flamed you win, STOP PLAYING RANKED !
If you don't care about winning or losing, STOP PLAYING RANKED !
Ranked should be a competitive place where everyone plays to win, i'm tired of whiny dudes doing everything else besides trying to win. Go play normals or ARAMS. Dense dandelions !
