There's a quest series in Azshara (and elsewhere) that is the only one I know of, with really good weapon rewards.
you get to choose between staff, dagger and sword. Info on this gear below:

I did the quest line and got the staff, which beats anything outside of BRD drops.
I plan to go with Nymph and Stonesalvo, but it takes a full group of 5 to do several of the quests in the series. The whole thing can be completed in around 3 hours, I think.
So we could use 2 more people with use for the rewards, one should be a fairly high level tank.
Please let us know who wants to go...
