And this is what you can't still get. The whole point of DW is that the talent in general allows you to equip 1H weapon in off hand while having 1H weapon in main hand. The same talent which frost dk and enhancement shaman have for example. In the case of warrior the last talent allows you on top of that to use 2H weapon in MH and OH as the talent specifically says you can equip only axes, maces and swords.
So my question is - if normal DW can not equip 2H weapon in either of both hands how you expect to equip polearm in OH?
