I already said it pierce armor better than sword, but it does not mean it deal more damage - quite the opposite against unarmored opponent. 
Also kafein, yes - chances are you'll die. Question is, how fast ? And wider wound means more internal bleeding and greater chance to hit vital spot.
Lactose, they are LONG, aren't unbalanced, have BONUS AGAINST SHIELDS and respectable damage (including stab) - and great reach. Not to mention good speed and cool damage against heavy armor.
well you do know they are the best weapon of the polearm category right? its normal that they have decent stats...

they are not that popular, not considered that op except maybe for poleaxe....
guys it's very nice to speak that a pleaxe would piirce better then a sword but if a sword peirces it would do more internal damage, this is kind of pointless...
and i want to make a reminder, this an internal poleaxe balance, poleaxe between them. if you have persqonnal grievance towards these weapon please create a thread of your own.
the elegant poelaxe is the most costly but is considered as the worst poleaxe
