Dual axe is actually the best for WB, especially the lvl70 green HoD axe you get which is really good, but one major down turn to it is that WB tend to go tank/aoe farm so two hander tends to be better because of the dmg burst either for aoe skill+range also I believe the 2handed lvl79 gold weapon is one of the cheapest high end weapon in game right now you can acquire for about 1.5mil which is extremely cheap compare to other gold weapon mold.
