I just invested time into research (scary, Ik).
According to Rune Data Base (
http://www.runesdatabase.com/item/list/0.4.1#items:-6-8+0 ), the 72 staff won't be better than our current best staff, Shackles of the Cursed Face. Staff of Wandering (Brown) is actually better than the 72 drop.
Not complaining, either. I could go a content expansion without wasting 2 days on making tier stones and stuff. Just letting you all know that you don't have to wait for better.
