Sure, the changes will be considerable, not not unova-levels of gamebreaking which is what I said. the main problem yeah is that the lower tiers wouldnt have access to the pokemon but yeah thats only 2/5 tiers that get the short end of the stick (ou, dubs and lc will be just fine)
Imho sinmoh brings like what, 12 mons? It isn't nearly as game breaking as the unova update was.
I'm defo all for taking a small break before playoffs and then going all in with the update
