I'm assuming you want another polearm since you mentioned your poleaxe. Scottish halberd is probably too similar to the poleaxe but it's very nice. You could probably trade poleaxe for it if you didn't want to have both.
Naginata is everything the glaive/long hafted blade wants to be.
Bec de corbin is the OP shitfest flavor of the month wep.
I don't know if you left before they changed this, but some of the 2D polearms (swiss halberd, english bill, long voulge, partisan) now have an alternate mode where they can swing left and right but have reduced damage and/or speed.
I have svaerdstav +3 and like it. It's very versatile - can be swung 4 directions, can stab with a shield, can stab on horseback. and It doesn't have shitty stab damage or reach either. It's a nice compromise between a stabby polearm and a swingy polearm. I loomed it because I really like the "winged spear" shape it has. Shit is literally a sword on a stick.
Spear and boar spear are 1 slot now, and boar spear got rebalanced to 24p on swings and stabs at +0. Interesting but probably not what you're looking for (?)
