Thing is, Paul is probably convinced that a 90 speed rating means that the glaive is exactly as fast as any other 90 speed weapon. He;s wrong though. Glaive and Long Hafted Blade have these crazy fast swings while having a ton of reach.
Shit is OP, atleast in duel, not sure how annoying the reach is in battle.
You're sorta right, but not quite.
The weapons speed explains the time it takes to finish an animation. And that's it.
However, there may be parts of the animation where the weapon is actually moving faster than others. It has been noted with polearm sideswings from the start, that the middle of their swings are unusually fast.
So yes, it IS faster than what the weapon speed suggests.
