Thanks for all the replies guys. I must say I don't agree that mh/oh is always better than a staff. I perform a lot better using the Abracadaver because of the haste on it than I do using my Heroic MS/Baton in Demo spec.
From my experience, Niebelung just doesn't seem to proc enough to warrant using it at all, but I was wondering if other had a better experience with a specific spec.
Thanks again.

From the stats on it, it looks tailor made for locks, though I fear some groups saying "healer preference" because it has no hit and has spirit
... if you don't need the hit, that staff is sexy as hell.
