@Donnerglut (and all) From what I understand, the flying classes in this one are all super strong. I know my Ingrid was nearly untouchable by the end of the game. Literally just getting attacked by 6+ people and never taking a hit from anything but the occasional spell, which she took no damage from because she had insane RES from being a pegasus knight. It was kind of funny to be honest, the last level took me a few tries until I just let Ingrid move up and tank everything. LITERALLY everything.
Also Edelgard would be well suited to wyvern lord with her axe skill. There's basically no reason to make someone something that isn't a mounted/flying class anyways, since you can dismount whenever you like and spears aren't inherently strong against mounted classes anymore. That was honestly my biggest gripe with the game, there was no real reason to use the non-mounted classes. Except for gremory that is. Gremory is insanely good.
