Path of Radiance is the only Fire Emblem I've played to date. How does that one stack up difficulty-wise compared to the others? I just remember Astrid and Mia being stupid-overpowered in late-game. Astrid having pretty much perma-crits and firing two arrows per turn from long range + having the horse mobility bonus. And Mia leaving her at 25% health for the Berserker bonus and First Initiative -- she could basically clear entire maps solo, as she always got to attack first, double crit and killed them every time.
