Re: so how is this fair?
yeah that's weird, but considering how you have to be at the queue the same time as the other players, the game probably chooses the most convenient player, no matter how high their rank is, else it'll take a while to find a match that's close to your rank.
I sometimes got matched up against players in the wood league, with peashooters and everything. Free stars, but must have been terrifying for them when a Three-Headed Chomper appeared.
