>>48348345I mostly just have a problem with how the best Gen 2 Pokemon are just handed to you and barely incentivize you to go out of your way to find more.
Pokemon like Mareep and an early Marill should have been the incentive to keep exploring a route, not absolute shit Pokemon like Yanma or Dunsparce.
Outside of that, the only big problem with Johto's distribution is with its trainers. Kanto gym leaders, especially the early ones, teased at Pokemon you could get later in the game (Onix in Rock Tunnel, Starmie and Raichu from the Celadon Department Store, Alakazam from trading). Falkner, Bugsy, and Morty would have all been great opportunities to tease future Pokemon like Delibird/Natu, Heracross, and Misdreavus especially.
Teasing a Mt. Silver Pokemon would have fueled a kid's excitement about what could possibly lie in that seemingly inaccessible area and help build a legend around Mt. Silver except at the very end because they needed a post-game dungeon.
