I of course appreciate the testers efforts but at the very least some of those results are demonstrably false. Polearm stab is not polearms shortest attack as shown by
waltF4s 2nd video. Based on that glaring mistake I'll stick with the old established numbers as they jive pretty well with my in game experience (6 gens of 2h followed by 7 of polearms)[but really I'd love nothing more than one of the devs to pop in here and correct me with their numbers.]
As for actual poleaxe balance, it feels pretty good.
-The poleaxe gives you devastating pierce damage and the range lets you footwork an extra hit now and then vs shielders. If you have to duel a competent longswordsmen you're gonna have a bad time. Still its excellent at its job and feels good to use.
-The german gives you the best cut and even though its less pierce than the poleaxe its still amazing pierce damage. Yeah you've got less range so you probably aren't getting any free hits in but that also means your weapon doesn't get stuck on as much shit. When I had it I was perfectly happy with it and if the poleaxe takes any nerfs i'll gladly go back to it.
-The elegant is in a wierd spot but seemingly balanced. The other members of your family are better at bursting shields than you. You don't do as much damage as your relatives but its still decent damage (stab is the same as bec stab and really you've never once had a bec user spin stab you in the face and thought, yeah that seems underpowered.) Its speed puts you in a pretty good position vs most everything so when you don't have any support it seems like a reasonable choice (of course its a tough repair bill to swallow if your team is getting crushed.) I can never bring myself around to owning one but whenever I pick one up i'm happy with it. I want to do something to increase its usage but I just can't figure it out. Basically if you took a German Greatsword and gave it polearm animations but on the plus side gave it the ability to break shields it would be called the elegant poleaxe so when you look at it like that I don't know how you could adjust it without making it overpowered.
