Why not slice, whats wrong with slicing?
Slicing ruins my argument ;) Besides the curved "slicing" swords all have increased damage anyway so that is taken into account already.
Okay, let me elaborate why your suggestion makes no sense. How long would it take to sheath the balanced poleaxe to your back? How long would it take to sheath the balanced flamberge to your back? What would make sense is making all weapons that are longer than 120 are unsheathable or something along those lines.
The next item on my list of requests was going to be to make all the polearms with large, heavy, metal heads unbalanced, but i was going for 1 thing at once
It doesn't make sense that the Voulge is unbalanced (length 124, weight 3) when the Long Bardiche (length 140, weight 3.5), the Long War Axe (length 123, weight 3.2), the Great Long Axe (length 125, weight 3.5), the German Poleaxe (length 131, weight 3), etc aren't. All the ones I named (plus more) are similar in design, length and weight (if not heavier) yet they are balanced.
The degree of annoyment when carrying a weapon on your back has nothing to do with 'unbalancedness' but rather with the length of the weapon. It still would be completely uneccesarry even when its based on length.
I'd take doing it based on length if it was also based on weight. So over 120 length OR over 4.9 weight = unsheathable. It achieves the same result as my main aim
