I was play Shaman as resto in Remix as tried. I noticed they drop staff and two hand mace from LFR.
Alwasy remember shaman resto REALLY must be use shield with one-hand.
But new thing dont need? Can wear two hands? Also unsure double one-hands too? All with intellect
Either as ele or resto using a staff is totally fine IF its an improvement in item level or better stats then 1 hand and shield, however a 1 hand and shield is always preferred due to the ton of extra armor you get from the shield
