It's still an upgrade for Savage or any other jobs that use onne-hit WSs, so it's a good piece to pick up, but CDC accessories remain unchanged.
Yeah, it's definitely good for many WS and I was updating my sets after getting the drop last night. BLU just gets to remain unchanged :)
BTW, how do you feel about Vampirism offhand these days for a more melee focused build (comments in the guide mention "with further testing, could make it a far better weapon than I currently give it credit for...)
I know high acc situations, Nibiru Blade is awesome. But when you don't need the extra acc, I've been using Claid/Vamp (near max augs) and been pretty happy with it - very good damage, the HP/MP/TP drain is a bonus (that I have a hard time actually quantifying), and it's quite nice to have MAB in a great melee offhand for the occasional nuke.
