Veering away from the topic of the XY Starters for a moment, you know what I wish they'd do in Gen VI? Provide us with a reliable and consistent way of getting Starters with their Hidden Abilities. Also female versions of them.
I dunno, something along the lines of what they did in HGSS with Professor Oak/Elm/Birch/Rowan/Juniper/whatever giving us the choice of one of their regional Starters after finishing the post-game, only this time, the Starter has their Hidden Ability. I would like that.
I would also like it if Chespin/Fennekin/Froakie had their "DW Abilities" as their defaults with Overgrow/Blaze/Torrent being their Hidden Abilities.
