Underrated builds for characters

Hey! I've been playing three houses again recently and I've been doing a weakness run where I have to use everyone's weakness and sometimes budding talent and throughout my playthrough which I'm not on black eages because I'm doing every route I want to compile some of my favorite builds that I don't see talked about and I want to everyone's personal favorite underrated builds for different characters

Bow Raphael: okay I'm not gonna explain too much as it's my own personal opinion on builds but for me personally I think Raphael does wonders as an archer unit as he has great strength with an okay dexterity but make him a bow knight and give him battalion wrath and he should be good to just one shit people

Flying flyan: this is a two parter as I have two different builds with flyan but they both include flying one being Pegasus knight and the other being wyverns; now making flyan a physical unit is already bad because of her low strength however I think her strength doesn't need to be high when you had desperation,darting blow and aegis for the Pegasus build but for the wyvern build I think both death and armored blows work best for her and that low strength ontop of pavise and I think if you mix aegis pavis and the 3 blows I listed I truly think she can be a good unit

Riding Dorothea: okay so I haven't finished the black eagles route yet for this challenge however I think that do far her damage output is out of the world she nearly one shoted death knight on chapter 6 and so far sword breaker and desperation have done numberd with this character plus the def +2 is a real big help

Bow sylvian: okay listen I know this is the second bow unit but hear me out okay, he has great speed, decent dex and great strength and honesty I built him off of crits which he hit very easily and since he was a hoe knight had amazing range and from there he was one of my best units of my blue lions run

Wyvern ignatz/lysithea/lindhardt : these next 3 I'm gonna clump together because they are all the same because they all do incredible damage and it's a wyvern so they can move far and a lot ontop of that ignatz and lysithea both are crit machines when I hit them so definitely one of my favorites

Okay that's all I got I would love to hear everyone's favorite underrated builds
