Also many pokemon are just rehashes of other mons anyway. Bibarel, Diggersby, Talonflame, and I guess now Vikavolt are the only regional mons that weren't completely interchangeable with the rest of their archetype.
Can you seriously defend three fire/fighting starters in a row, with the likelihood of a fourth fire/fighting starter on the way?
Even if we had a thousand mons it wouldn't suddenly feel like a real world because the games have terrible worldbuilding.
I wish regional forms were introduced sooner. It could have stopped the Pokedex from being so bloated with fillermons.
