To me the problem with FE is the quantity, not the quality. If Everyone is Here wasn't a thing, multiple other series had the same amount of characters, or FE didn't get a high amount of newcomers in 3DS/Wii U Byleth probably would've been a decent reveal - but when FE, a mildly niche series that only really has a fanbase within the Nintendo community outside of Japan, has more characters than series like Donkey Kong, Kirby, Zelda and god damn SONIC THE HEDGEHOG, then it's a problem, and stripping Byleth of his sword or revealing him earlier the Fighters' Pass wouldn't change a little bit.
