Whats your hit and expertise at? You need a lot of hit to DPS properly as fury. (Just like any other dual wielding classes: Rogues, Enhance Shammy, DW frost Dks)
I wouldn't go even touch fury when i 1st hit 80.

Seriously, Arms>Fury at lower gear levels. I assume you are wearing gear from Reg/Heroic TOC since you are a new lvl80.
Reg/Heroic TOC plate gear has almost zero hit/expertise in them. You can't expect to wear that for Fury dps.

Ppl need to learn that holding 2 BIG weapons doesn't means you will have higher DPS.

Sword, Mace, Axes. http://www.wowhead.com/?spell=46917

Polearm is not included. Loot Master fail lol. /facepalm

But the ArPen and relatively slow speed 3.5, makes it a fairly decent Arms weapon. Too bad its has no STR.
I still wont roll it against a drood or hunter for it.
