X and Y did change the game for the better...
BP are still piss easy to get with new, awesome items
A lot of strong, and useful pokemon for online battles like Aegislash, Talonflame, Greninja, Diggersby, Trevenant, Goodra, Barbarncle, and Klefki
Mega Pokemon that have shaken everything.
Easy training and breeding fixes
Hex Maniacs and Female Breeders
The only downside to X and Y is really just some Pokémon are still unobtainable like Totodile, Cyndaquil, Turtwig, and many legendaries.
