I would disagree with you when you state that a warlord with a polearm and secondary weapon is too powerful. Against mobs it is quite incredible, but as you know, forms work quite differently in player to player combat. With my voulge and current equipment I can OBLIT through sanc, and *occasionally* ANNIL, but in all the duels I have fought with it I have only hit a form that strong two or three times. An item like the voulge really does not add to a Warlord's strength because of it's potential damage, rather it is incredible because it is noremove, and extremely heavy.
On the subject of Warlords use of forms, yes it is very amusing. Almost without exception every new warlord strives to have two weapons dealing damage forms. Eventually when they finally get a clue you almost never see them with a sword/axe or polearm/sword combo. Personally, I would prefer the voulge to have another form associated with it for dueling purposes, though the unspeaks sure are nice.
