S, A, B. Score Vs win/loss
As in SoloQ you don't have control over who you get as teammate, afks, etc. Couldn't people (in soloQ) be ranked using the individual ranking you get at the end of the match (a+, c, b-, etc.)
That while retaining the win/loss system for 5v5 teams which do control who they play with and they don't rely on randomness.
