Pokemon Champions looks interesting, but I'll be disappointed if it doesn't eventually include all Pokemon. At the very least, it should be compatible with everything but rotate for different years or whatever. People said it was cringe to care about Stantler and other shitmons back in SwSh, but I don't care. The freedom of using any Pokemon from across the catalogue against friends or randoms online was fun.

For other grievances, there are a lot of weird little changes that just confuse me.
