I'm STILL waiting for a dunsparce evolution D: it's just so necessary its almost unreal.
Tropius definitely should have an evolution to complete it, by either getting a boost in Sp. Attack on in Speed.
Luvdisc would be nice to have an evolution for, it's not really necessary but it'd be nice to know that this pokemon isn't a waste of time, breath, life and words.
I really wanna see some Feebas ---> Milotic-style new pokemon evolutions, just with different attributes than Beauty.
I really hope that Torkoal doesn't evolve though, it's just really cool as it is~
