Within 1h, the pierce/blunt weapons do more damage than the cut weapons to everyone. Yet within 2h/pole, high cut weapons do so much damage to everyone, that there isn't much incentive to take a pierce/blunt weapon for fighting high armor targets. For instance, right now a Great Long Axe (45 cut) does the same damage to 60 armor as a Bec (34 pierce). Why take the Bec when you can do more damage to everyone and break shields with the axe?
1h are being forced to use the pierce blunt weapons (and deal with the terrible reach) because 1h cut is so awful on loomed medium armor or higher. 2h doesn't have a care in the world, because their loomed greatsword does huge damage to everyone.
