It would be even (2h vs polearms) if there weren't so many 2h cunts abusing lolstab and using macro feints.
Still, polearms left swing is godlike imho. And overhead is better. Also those two Axes, Long Axe and Long War Axe are so broken that I almost won polearm duel against Tor, while wearing ragged outfit. He had his Mighty GLA, I picked up someone's Mighty Long War Axe from the ground. It's so much faster it's not even funny.
Polearms OP weapons: Awlpike, Ashwood Pike, any of those long stabby polearms (Swiss Halberd, English Bill, Ranseur, Spetum, Partisan, Long Awlpike), Long Axe, Long War Axe, Poleaxe, German Poleaxe, Long Bardiche.
Twohanded OP weapons: Greatsword, Sword of War, Longsword, Heavy Bastard Sword, Barmace, Long Iron Mace, Great Maul, Mallet, Great Bardiche, German Greatsword, Miaodao.
They are even if you ask me. Also one handers are even with both.
