Great post elindor! Only 1 more thing: Unbalanced weapons are slower to raise up, but faster when u actually release them.
For example, with +3 Great Long Bardiche 88 speed, and +0 poleaxe 89 speed, if both weapons are raised and release at the same time, they are almost equally fast. But it took longer time for the Great Long Bardiche to raise up and be readied for swinging
