Opinions on My Laegjarn

My first post on here! :) I came up with this build and decided to see what it would look like before I start building it on her in my game.

Some context: I am mostly a F2P player with limited fodder to work with and do plan on S-supporting her, obviously, and I want to give her a +Def refine on her Slaying Edge+ because of her -Def bane I happened to get on her. (Nothing that can't be fixed right?)

Any opinions/thoughts before I go all-in on her?
