>>55861922Old gen players decided they wanted to be real metas too. RBY players "unfroze" OU allowing for Pokemon to drop from OU and creating UU and NU. GSC has mostly been untouched, and ADV only really banned Sand Veil, leaving Baton Pass and Arena Trap and everything else unchanged. DPP allowed Latias to drop from Ubers to OU which killed off Lucario and Infernape's viability, but aside from Arena Trap and Baton Pass being banned, and the Snow Cloak ban (RIP Froslass), nothing has changed all that much banwise.
BW is the first old gen to specifically ban a Pokemon that was legal when the gen ended AFAIK. ADV accidentally banned Cacturne because it only had Sand Veil, and DPP accidentally banned Froslass because it only had Snow Cloak, but there's nothing they could do outside of a complex ban to keep them legal.
