The crit damage is a reference to BB's self modification lol.

Her NP gain isn't that high. Melt/Sitonai still higher than her and easier to use. She is the kind that hard to utilize but OP if you used it well servant. Not braindead comp like double merlin/tamamo/skadi

Well in CCC Foxtail Manga if that make you feel any better.
