First brutal playthrough. I love flying units, and I decided to make every combat unit a peg knight/dark flier this playthrough.
Got Lucina, Sumia, Redhairgirl, Olivia, Cherche, Cordelia, Severa, and Cynthia as my combat units and they are all flying.
However I reach ch.19/20 and I can't beat the chapters. I get 1 shot by warriors with bows. The brutal heroes and paladins can beat my dark fliers 1v1.
Do I need to reclass to beat the game?
