Fodder my Amelia?

What's your guys' opinions on Amelia? I mean she does have amazing stats, especially since she's an armored unit, and she has the essential "Armor March" C-skill, but nonetheless I still keep finding myself going out of my way just to keep her alive in almost every arena match and high level pve match. She's basically just a BK escort, helping him move around the map more easily then having to dip out right away before she gets exploded by anything....

I have Fury, Renewal/Desperation (swap between them depending on what I'm using her for), and ofc Armor March. She's also got +spd and -res, so pretty damn solid. But regardless, she just feels like kind of a liability. I also have a Hector +1 still and I tend to just swap him into pve matches where I don't need my BK to move more easily cause Amelia is rarely necessary outside of that skill, and I even have more success with him in arenas. He's only +hp -res, so nothing special but good enough (both Hector's had the exact same boon/bane... ofc...), but again he still performs so much better then Amelia in nearly every situation.

So I'm wondering, should I swap off my BKs Panic Ploy once I get the seal for the same thing and give him Armor March, with Hector and his Goad Armor as my new duo-armor-buddies? I know they fill the same niche, bait in the appropriate colors and then vantage everything to death, but using them both at the same time hasn't left me feeling like I wasn't making use of one of them for very long if ever. Unlike Amelia.

So, what do you guys think? Did I just not build her right? Is there another way to do so that I'm unaware of? Or is she simply not as good as Hector or BK and if so should I just give her C-skill to BK?
