The extra Def ain't really worth it imo as it seems like she wants to fight mages and dragons. I think you should fodder her sweet b-skill to someone who hates fury damage but needs the stats.
Well her HP wasn't doing her any favors in the first place, and her DEF is only beat by Delthea. Personally I'd keep the Neutral one but apparently everyone on this site hates neutral IVs and I don't see too many downsides to +DEF/-HP one so go ahead with that.
