I personally think that Nelis at 1.5 is -insanely- abusable and I should've given her a base score to work with. I think 2.5 works for her, although I now have to wonder what does Geddoe do that she doesn't do almost as well -at least- (no OHKO damage, but she more or less almost always 2HKO off MT damage she has a lot of charges of, and her MT damage has comparable speed to his OHKO, and she has more charges and more MT... I can't help but think he could go down a bit with the comparison, even though he has more durability). Oh well.
EDIT: No matter what, good MT damage off speed that doesn't suck is always insanely valuable in the dungeon, and Nelis more or less fills the niche from the get-go. Not to mention she has very good magical durability and her physical durability isn't a liability. She has no truly easily exploitable stat failings in the Dungeon - even with the easily walled element, that's worth a lot of points, especially considering the source of damage (magical damage >>>> physical in the dungeon).
