The thing is, when player count is low, game puts together people from a big range of ranks.
I was just in an Oracle game, altho I am not even an Archon rank.
I think many problems could go away if ranks of everyone are simply laid out before the game starts. With knowledge of everyones rank, i think this would also generate less false reports about smurfing and whatnot, because maybe that person is 2 rank categories ahead of everyone and isnt a smurf, its just the game matchmaker doing a funny thing.
