I agree on FE being way over-represented. Honestly, what a joke. 3 characters at most would've done, but with Corrin it's become apparent that Sakurai is just outright shilling the franchise and using Smash Bros. as an advertising billboard.
I don't see the problem with Gannondorf's moveset...
As far as speculation for the new characters is concerned, Banjo and Kazooie were by far the most popular votes in western Countries, but I'm backing in Midna & Wolf Link to join the cast mainly. The Amiibo is reported to work in SSB and it would be practically free advertising for TPHD.
B&K...
