Someone has done this?

You could, but I doubt we'll see much of this now that Thunder Armads is a thing.

Quick Riposte isn’t too useful for him because of his Maltet in my opinion.

Hmm... Interesting. And Wary Fighter works well with Maltet due to sharing an HP threshold. If the QR seal wasn’t occupied by Fae, i might try this.

Eh. Not bad, but this build was prevalent before Bold/Vengeful/Special Fighter were widespread. He's plenty tanky as is so I'd rather have my cooldown.
