Oh, I agree on all of your latter points was more of a "what if"?
You have capped accuracy at harder dynamis? I'm not saying this in a nasty way, just genuinely interested because I never feel like my DRK has capped accuracy on those and my DRK's accuracy is leagues above my THF's.
Limbus depends too much on the floor etc, I don't think you'll hit cap on Proto-Ultima etc though ... might fall under the category of "who brings a thf to this" though <_<!
