Agreed.
I think if you want to take a crack at something unorthodox you should actually try this:

Basically, using the F+R setup but swapping MoC for Aughild, and trying to make up the toughness deficit with Stone Gauntlets. I don’t really think this will work - probably too fragile- but it does do a bit more damage than the regular F+R setup.
