"Quickly re-learning a lot of evolutions aren't actually in Gen 2"

#PokemonGO: The first time I saw a Sneasel I was really excited at the prospect of evolving into a Weavile, who like in the games, would be a decent Pokemon (I would think).Then as I looked at my Sneasel's page, there's no evolve button! I looked it up, lo and behold Weavile is introduced in Gen 4. Same goes for Ambipom and Gliscor just to name a few.Aside from Gen 1 --> Gen 2 evolutions which are classic, I kinda just assumed most evolutions were within their own gens. It seems kind of silly to be "saving" Sneasel candy for an evolution that's two generations later... but what else am I gonna do with it? via /r/pokemongo http://ift.tt/2kJpG2l
