Well, then you get into the other spectrum of disappointment: uselessness.
400 more damage (200 in PVP) and 200 more health gained back, and the only way to eclipse the final 200 Nanoskills is to dump EVERYTHING into building your nanoskills up via equipment, perks, both drains (one of them being 150%) and the like... and that's what you're rewarded with?
That's uselessness.
