Hold the phone here for a while. Sure, one can say UU is more overcentralized as OU but correct me if I'm wrong, but OU has a big amount of pokes to choose from. WAY more as UU has. So... 256 Pokes are usable to OU. 42 are in the top 75%. Ergo, 16.6% of the pokemon available are used in the Top 75% of OU. 156 Pokes are usable to UU (That is including the new additions though) 39 are in the top 75% Ergo, 25% of the pokemon available are used in the Top 75% of UU. Something seems odd here about your argument suddenly.
