The new Fire Emblem games have sold amazingly well and saved the franchise from the dustbin so it's really weird to complain about the stuff they did to save it. I mean would you rather have Fire Emblem the way it is today or no Fire Emblem at all?
Fire Emblem Awakening's success had nothing to do with "otaku pandering" (the more fan service-y art direction can be attributed to Kozaki and Kusakihara than any form of pandering) so much as it does with making the game more beginner friendly after Radiant Dawn's brutal difficulty killed the series on home consoles for a decade and putting together an actual marketing campaign in Europe and North America for the first time since Rekka No Ken's mediocre attempt with the now infamous Dorca poisoning "Trust No One" commercial. The fan service-y designs aren't necessarily out of place given the Castlevania series history of similarly tasteless designs but I can't imagine your average consumer will look at the character designs and be drawn to this game. If anything, I imagine it would turn them off from the game.
