And the 2h's in that list are either faster, or deal more damage than their counterpart.
Ahh a change in argument, very clever. Damage and speed are pretty simular actually.

The only real outlier is the war spear, which has low swing damage, but higher pierce damage.
@Zerran: I will give you the fact that the left swing sucks on polearms, and that is an advantage to 2h but you can generally avoid situations where you are forced to left swing.
In a vacuum, I would say that 2h have more fluid animations, but personally I think most players are so accustomed to their animations that they are pretty predictable compared to the GLB or glaive.
