Just a quick point on 2h weapons, even battleaxes maxed out at their heaviest at around 2kg so 5kg is pure fantasy, longer weapons travel faster at the end (simple physics try it with a 15 cm stick and a 60 cm stick), you can pivot round the upper hand to add swing speed and you swing it with 2 hands adding acceleration and manouverability. The only advantage of 1h over 2h is that you can use a shield. 1h faster than 2h due to simple physics, hmm. Try it with a friend. Unless weapon is very light and whippy, and hence almost useless versus any armour, my messing about makes me question that statement.
