Matsuri should probably be power based instead of level based, I'm level 56 with 21k power, how do you think it feels for all the other level 50 people who only ever have 6-10k power at most to find someone like me in their level range when they're often a couple levels higher? probably pretty awful, at least though my 4th/5th fights are with lv75 people who are at about 18k power so it eventually evens out.
This reminds me.
Arena needs to not be cross server and they need to widen the matchup or something, it's impossible to make progress in arena when all you encounter are Kage teams or super spender teams.
