If they make a fire emblem 6 echos, i would kinda like to see fe 7 out in there was like a pre story ( this is optional maybe dlc?). Some way to know about who the mothers of roy, Lilina , sue are. I also would like to see buffed growth rates like they did for shadows of valentia, binding blade seems to gave lot of characters like armored knights that don't turn out to well , expect Bors. Also on the subject of knights a movement buff if they would keep the maps the same size. other then that i'm fine with whatever they do. I'd love them to bring back the magic triangle they tossed in the garbage in awaking
