And you still have mechanical bloat with all of the moves being the game (They've gotten a lot more complex since Gen 1). Megas and Alolans (Pokemon can change type mid-match now? This Vulpix is Ice Type?), Natures, EVs and IVs (And whatever candies do on top of that).
Realistically, the game should actually be adding stuff to make learning this easier. Why isn't there somewhere were you can see what all the natures are and what they do, how does your pokemon evolve, if it does evolve (What level, or if it requires an Evolution Stone, if it can Mega Evolve, etc..), moves that a pokemon can learn from levels and TMs. This stuff should be in the game, you shouldn't need to search up Celebi or Bulbapedia for this knowledge.
If only there was some Pokemon Database device Professor Oak could create... some kind of Pokedex that could hold all this information a trainer would need and would be accessible from the pause menu when a trainer needs to look stuff up about their pokemon...
