There's barely a single Archanea character that's going to give the huge sales people see from Three Houses, Lyn, Camilla, Lucina, etc. Only Marth, Tiki, Caeda, and possibly Catria will ever come close. No one else. Because of that, I feel like people don't really give it a fair shake and always underestimate how many semi-relevant characters are left. The Grust kids, Lorenz, Midia, Xane, Arlen, and Wendell all feel like they're notable amongst the other Archanea characters, and none of them have base forms yet. That's a couple of banners right there if they can find the right alts/OCs to pair with them.
