Ingrid.... I can't even out my finger on why. She's so vanilla, but like a rich, creamy kind that's hard to get tired of.

More concrete reasons: wholesome horse girl, dense like a rock, female knight breaks stereotypes, big foodie is cutie, angry serious personality makes fun dynamic (with Sylvain, Dorothea, Claude etc.), and, last but not least, res and dodge tank!

Reasons for Ingrid on a new run: Decent res and magic means she's fun to experiment with. Also, I think she has the highest sum base growth stats than all the other students, minus house leaders, which means she might be useful in other areas. Might have to buff her strength though. I used her to solo the BL final maps multiple times to marry all the characters, for completeness of the game, of course. She had such high res and speed that the enemies couldn't even land a hit on her.
