To be honest, I still find myself scratching my head over the fact that toon link still wasn't changed to reflect his own series more rather than just copy-pasting link's toolset with a few tweaks OR cut. The fact that neither happened boggles my silly lil' mind
I think the only thing that could make me go into a lil hissy fit as much as Toon Link's reveal showing nothing major had changed would/will be Chrom getting in. I don't even care if the blue-haired lord's moves are a beautiful, unique snowflake; my sense of aesthetics rankles at the mere thought of another person from the same series with the same general look

While I agree with Golnei's assessment of Shulk in the previous thread (which was a beautiful read, by the way :3 ) Chrom bugs me way, way more.
Snake? He could be replaced with an assist that traps someone in his 2 person love box with him for a few awkward seconds and massive percent damage for all I care, though for snake die-hards I guess it would be nice if he made an encore appearance (preferably with fixed hitboxes)
