2h fury will only work out on horde side in mc ,till max bwl.2h melee speccs /classes are simply not viable for pve in classic. you will deal more dmg with 2 1handers.
but you asked for a specc. here is one:
-no imp Heroic Strike cuz you will use slam if you have to bump rage.
-hold Bloothirst and Whirlwind on CD
-if there are tons of enemies and you have to bump rage, use Cleave but spare rage to hold WW on CD.
-your overpowers will hit hard, use them always
but i already mentioned, you will deal less dmg then 2 1h fury.
