I really want to see a well done pole weapon user. The biggest one being a proper glaive user. One thing games tend to forget is pole weapons can also be treated like blunt or slashing weapons on top of piercing weapons. It should be able to mix piercing, blunt and slashing attack and should have retain that versatile aspect.
I would also like to see shield and bucklers better differentiated, shields should have a substantial stamina and speed drain. Actually the difference between light and heavy weapons and armor should be better shown with their effect on stamina and speed. I am not sure how hard it would be to actually balance though.
