Finally, my stance on Fire Emblem. Keep in mind I'm a hardcore fan, played every game in the series except for SoV and Three Houses. I think the representation is a mess. Sakurai has done a terrible job in representing it and showing the variety of characters it has, and the number of characters, while it might be representative of a storied franchise that's also a rising star, is still overbloated and handled the franchise's growing pains in the worst way possible.
Simply put, we don't need a Fates representative, and as important and amazing as Awakening was, we don't need three reps from it either. What we do need is to feature the most popular games, in ways that feel unique. While some characters (Lyn, Byleth) are very easy, we also need Sakurai to put on his thinking cap and find ways to make these characters unique. I get that maybe there's so many things you can do with a sword, but there's no reason besides an unwillingness to be creative for Roy and Chrom to be Marth clones - there are many ways to wield a blade and we've seen them fight in their games in ways that are very unlike the Marth style.
Now, granted, many of these problems are just symptoms of everyone having to return, so hopefully a new game would make things better. As is, sadly I can't begrudge anyone for loathing the possibility of more FE as DLC. And while I think the hatred for "anime swordfighters" is unfounded, it stems from this and it can be easily fixed. As a Fire Emblem fan, I want nothing less than for people to hate the franchise, but I don't blame them, I blame the poor decisions that made them hate it.
