But if the usage stats are the only thing we're going off of, shouldn't bad pokemon that get tons of use like cloyster be in OU?yeah usage stats are based on the base forms and mega evos are just thought of as a different item (charizard with x stone, y stone, specs, salac etc are treated the same in tiering)
Either way it's a silly thing to go off of, they obviously wouldn't be overpowered in lower tiers without their mevos. All it would do is allow some more variety in those tiers.
