Increase the matches needed to 30, per month
I would love tiers added, honestly I would like to create a new stat for how valuable a player is, using a few stats, Baseball has a lot of different examples of things that could be modified to fit here. Like WAR, or in this case it would be PAR, Pilot above replacement. Or something like that, Jarls list has a nice thing working but with more stats available we could do something more even. Weighted by mech size, tier, average match score.
