This so much. One thing is to disagree with the character selection; another completely different - and disrespectful with developer's work - is to call this a trainwreck. They clearly put a lot of effort into the selection process, even if we don't agree with the results. I'd love a more diverse roster, but it seems you can't enter a FE Warriors thread without the same complaints being repeated over and over.
Eagerly awaiting more reveals and the release date, although I'm not sure I'll have the time to play that much considering M+R, SMO and XC2.
I'm sure some of it is fatigue. People are starting to get tired of seeing Shadow Dragon/Awakening/Fates in every crossover:
1. Practically every single FE-related crossover in the past while has already drawn from 1, Awakening, and Fates. Smash Bros. has those plus one from RD and Binding Blade. Project X Zone 2 has two from Awakening. Tokyo Mirage Sessions is exclusively SD and Awakening. This is the fourth major crossover in the past three years that mainly draws from those games. Eighth if you want to count amiibo cameos in Fates, Steam, and Mario Maker.
