One thing that bugs me is that you see (for example) Rapiers used against armor...
Which always bugs the hell out of me! They are not good for that! Estocs are, rapiers aren't.
What I would like to see is a clarification of what weapons are civilian weapons and what weapons are military... ie, military weapons are useful in battle and when people are wearing some form of armor. Civilian weapons, because they *aren't* useful against (say) the armored Town Guard, can be worn for civilian self defense. And people wearing large amounts of armor would get stopped in town by guards who are like, 'Who are you planning on murdering, bub?'
If you want a rapier-looking weapon for use in war, use a cut-and-thrust sword. Rapiers and Smallswords, despite being piercing weapons, are terrible against armor...
But I would like to see people having a particular 'walk around town' kit, due to legal restrictions, for at least some towns... only light chain that can be hidden under shirts, non-military swords, whatever clubs you can find, no helms, civilian swords, etc.
