Thing is I'm not necessarily asking for a change. When people sign up is like a contract, you know what you get into and as long everyone agrees it's all good. Like the first one where no legends were allowed but breedabke Ubers were, I thought it was kinda ridiculous to have Mega Mawile or Mega Luke but like Lati@s or Meloetta banned.
Regarding the bans, they are somewhat different than the "logic" (don't get me started) in OU for bans. Basically a Mon is gonna be banned if it guarantees an autowin versus at least three types. Lando-I for example is allowed because it doesn't meet that criteria. Meanwhile, Mega Metagross was autowin versus Ice, Fairy and Rock for example.
Also like I mentioned initially, it is very matchup dependant so some types suffer more than others. For example, Normal could handle CharX but Electric couldn't touch it almost
