It sounded to me like you were using a Polearm in "Two-Handed" mode and were wondering if it benefits from Two-Handed skills as well as the Polearm skills.
That's exactly what I'm asking. It's a confusing thing to ask about maybe because it's apparently kind of hard to explain, but I should have tried a different way to explain it in the OP.
As I said in my other post, polearms are not 2h weapons. They are polearms. 2h weapons should be called '2h weapons that are not polearms'. Ditto for 1h.
If that is the case, I think it would be an interesting change if both perk trees worked for a weapon that is being used in that way, but I guess this really only applies to polearms since it's the odd man out. The issue, to me, is that polearm is a relatively bad perk tree, including things like extra couch damage which is useless because couch without perks already kills everything instantly, and then there is that one hand and two hand trees include a lot of perks like increased damage or speed, but polearm doesn't have that... so when you find a polearm that you want to use that isn't just a typical couching weapon used mainly for horseback, it ultimately appears as a very weak alternative to just using a one hand or two handed weapon instead, especially considering they are overall not exactly the best choice when playing on foot.
All this comes from finding an awesome polearm last night that is really fun to use because it's not a typical polearm; the Rhomphalia... a 203 length, swinging weapon for 169 cut damage. Doesn't even have pierce on it. I mean, a lot of the polearm tree just doesn't even apply to this weapon. It can't couch, it doesn't stab, so it won't knock back, etc etc.
