I looked at Alphonse and some of the Deadly Sins/Homunculi. Since the extent of what I know of this anime is that there's a bad dude named Scar and a guy fuses his daughter with his dog, all I can say is...I would not have the patience to work with the numbers, and the Crest of Truth sounds interesting.
Oh, and on Melia having lance as a budding talent, I think the Alcamoth soldiers use spears, so I was kinda reffing that. She also has Spear Break.
On Dunban with brawling, remember how he socked Mumkhar right in the kisser at Valak Mountains? I was reffing that, perhaps this version of him has both arms good. Although he really wouldn't be himself without the stiff one armed swagger, I admit.
