To evolve... or to not evolve?

Evolve unless the Pokémon can only learn specific, good moves in its previous form. That or if I can just level it up two or three more times to learn an awesome move that the evolution would take 10 more to learn. Or if it's just not as cool/cute-looking to evolve then you know.. I'll just try keeping it the way it is forever. ; ; Even if that's not always viable lol.

i always evolve unless im either doing a challenge or i have to wait for that pokemon to learn a specific move but ya otherwise its gonna evolve eventually :D

I always tend to evolve Pokemon, because you do need strength. For some stone evolutions I tend to wait for certain moves before evolving them.
