well as im sure your aware the weight nerf affects your wpf and MOVEMENT speed so increased weight is a bad thing.
Weapon weight has nothing to do with WPF penalty. The actual difference in weight isn't enough to significantly slow you down
Also trust me the weight is not high enough to stop yourself being crushed by a real crusher, atleast not on EU.
Well... yes and no. A great maul and a boulder-on-a-stick (aka long maul) will crush through it consistently... if the opponent has a high enough PS rating and a decent speed bonus. If they mess up their speed bonus badly enough, the extra weight can make a difference between a crush-through and a regular block.
Secondly, you're not factoring in the most important part of heavier weapons: weapon stun. If you are using a very light weapon like a scimitar, and your opponent is using a heavier weapon, you will experience a "mini-stun" when you block a hit. A lot of the complaints of "2 hand spam" come from this. Having a heavier weapon will prevent this mini-stun, and make it much more difficult for an opponent to mini stun on a properly charged attack. This is a very strong benefit.
If you compare this to 2h for example the top ended greatswords offer far more damage or speed than the mid teir weapons .
apples and oranges here. Great swords don't have this enormous difference in pierce damage, and no sword has that highly appealing bonus to shields.
Ive used both weapons extensively and please explain how the poleaxe is "More versatile"?
This has already been covered quite well by Rhaelys, and I see no reason to add to it at this point.
Yes bonus against shield sis great when fighting 1h's, but up against a polearm or 2h your at a disadvantage compared to the glaive in almost every way.
Nothing could be further from the truth. You don't think
an extra 9 pierce is an advantage? Its a bit shorter, but in tighter quarters thats not a big disadvantage. I use the bec, and there are many times when the weapon's short reach has won me the fight. The speed of the two are almost the same, and as I covered earlier, the extra weight is very desirable against a 2 handed weapon. Poleaxe is a much more well rounded weapon.
Further evidence of imbalance is shown as a masterwork glaive gains far +2 speed whereas a mighty poleaxe recives only +1.
That might need to be changed, but the weapon is fairly well balanced internally.
