Wait, how do 1 to 3 vs 4s happen anyways? I've had moments of me getting a team of 4 before the Splatfest match, and then I suddenly enter minus at least one player, and not because of disconnecting.
Also, I don't like the idea of being shoved onto a team with a theme you don't prefer just because there's no equality. I agree that it can be bothersome to people facing their own team, but in my personal opinion, I think that doing that and getting rid of the popularity score are the best bet for Splatfest right now...although I feel like you're onto something with team quantity affecting the population of matches.
Also, sorry, but can you explain in more detail how you got those ratios? I still don't comprehend what you did there... Am I just derping on that?
I'm more bothered by at least what I perceive is their logic, not so much by winning or losing. It doesn't help that the rules for determining scores were hard to find, not to mention not even said anywhere in the game until the results are tallied.
