Specifically, a lance from my eyes would be like the UGS of polearms. Very long, powerful, and slow.
Spears should be slightly reworked to be less abused.
And from demos, the halberds are spot on.
But why should From stick to their conventional 1-2-3 weapon class system if they don't use it for all weapon classes?
Axe < Poleaxe? < Greataxe
Spear < Halberd< Lance?
Whip < Flail< ???
Mace < ??? < Greathammer
Just from small things like this, From could potentially increase diversity in combat two-fold. Feel free to fill in the blanks accordingly.
