I wish Mightyena was able to compete with the other pure dark pokemons, like absol and hoodoom.. (they both got mega evolution for some reasons btw..) If only they’d just bother giving it a decent moveset, or a reason to use it over absol and hodoom and etc.. (btw, I’m not even talking about competitive play yet, just in the “campaign”) Or maybe give it another evolution, or a mid evolution, and just retcon the fact that we never seen it before, like they constantly do.

And its ability is kinda bad now, given lots of pokemons have abilities to counter it anyways, or can just buf themselves to nullify it..
And now that Fairy is a type, it complicate things even more..

I’m just saying this, because I’m guessing their goal is to make each pokemons useful in a way.. And I kinda like those pokemons for some reasons.. Hopefully, it could be worse. Look at liepard.. Anyways..

As for the other forgotten pokemons, there are tons of them! Lots of pokemons I’ve seen and remembered from gen 1-2-3-4 are apparently less “tweaked” for the changes in X/Y than others..

Raichu can’t even learn any fighting move anymore, or iron tail, or even thunderpunch..(Yeah, pikachu got voice acting and random other things, but I’d still rather evolve it. Partly because, that voice acting is annoying.. ) Rattata was just deleted from existence, which is sad, even if I wouldn’t use it..(at least according to serebii.. No more top tier rattata 😛 ) I also haven’t seen a shedinja in ages!(quite a unique and interesting pokemon, even though its use is very limited)

I could go on, but I’m guessing someone else will do it anyways..

Its has to be ledian I forgot about him and ledyba, may be the most obscure and forgottten one out there.

I don’t even know what a Duranle is :p
