Instead of dropping majority of the older pokemon I would like to see them to have a patch or a series of patching to allow them after elite four using something like PAL park, and implement something like the Smogoon tiers they have the technology to do so and it would keep them from having to ban certain pokemon. I honestly don't care for any of the gimicks except for maybe the alola form pokemon but in the end didn't care too much about those either. I would like them to do something similiar to gen four and expand on pokemon using evolutions to bring relevence back to some older but decent pokemon or just older pokemon in general like dunsparce
