This is a good question!
I would like more exact values with units; such as length being in cm (I know, it probably is but meh.) and speed being how fast it will swing in seconds, with 1 wpf.
Also, I think it could be cool if some weapons had variation in swing speed, such as the longer weapons should have poor swing speeds, relative to their stab speed.
This could be told by say, clicking on the speed then it would have the % of the base swing speed, which the swing you are looking at takes.
Take a Poleaxe for example, which has speed 89; which could (it doesn't, I'm making this up) equate to a speed of 1s. The stab speed could be 100% of the speed, or perhaps more because, to my limited knowledge, I would've assumed that Poleaxes would be for stabbing because they would be very heavy in real life. The left/right (these could probably be interchangeable) could be 85% and the overhead, because it is so long and heavy, could have a measly swing speed of 75%.
This would equate to the overhead having a swing speed of 1.3s and the stab remaining at 1s.
WPF could reduce the speed of a weapon by a set value, for example 1 wpf= 0.01 sec faster (this is probably not enough, I've no idea).
In my opinion this would differentiate weapons from others and allow players to select the exact type of weapon they want for their playstyle.
what does 1 speed translate to in wpf terms?
Sorry for not answering your question; I've no idea but this could give us more of an idea!
