Both fury and arms are doing terrible in PvE. As in second last on most bosses, third last on a couple. Only rivalled by ret for bad DPS.
we are not topping meters, but we aren´t that bad at all.
One thing they could do without hurting PvE is put HS on GCD, other than that idk.(edit: although this would hurt tanking a bit).
actually this would hurt pve dps alot.
