Yeah I was like WTF when 4th gen came out.
But yeah, I don't really give Banette too much attention thus don't really analyze it. Survivor has really made me gone from indifferent to hating Donphan though. And they made me go from loving Hoenn to being indifferent to it too.
I mean just because one region is better doesn't mean all the best Pokemon come from it. I have a really broad taste in Pokemon (except for Kanto which I have like 2), but my favourites aren't from one region just cuz I like it.
