berserkers are about 2h. At least in live. Personally I always saw them as dual weilding 2h's and going berserk.
I agree with the 2h part, but with the fighters guild giving them the ability to dual wield one handers and the vendor offering the 1h alternative, it could be a viable choice. Like I mentioned before something like a frenzy proc effect would be nice on the epics triggering at a higher than normal rate (not too high) with the possibility of damage augs as well.
I would still like to see some form of an upgrade to Destroyer's Volley to be on par with epic damage output as well.
