The bolded... i know it's an opinion but i strongly disagree. Xenoblade's designs are really beautiful, personally i feel they're a lot more interesting than FE ones that go a lot more quickly into the generic anime zone (not that i don't like them, i just think Xenoblade one's are a lot more original tbh)
And Duck Hunt dog is clearly a joke character on the roster (like Phoenix on MVC3), trying to find some sense in it is silly, just relax and enjoy them dude.
(I'd have loved Kumatora, though, and i hope Lucas comes eventually)
I am relaxed, that's why I had the trailing "but whatev". I think that the roster looks good despite the couple backward steps from brawl (no IC, PT split up, Zelda split up, 3 Pikmin) likely caused by the need for parity between 3DS and Wii U versions.
