1. Greater variety of large weapons (two-handed) like: greataxe, greatsword, halberd, trident, double axe, scythe and two-bladed sword. Of course, the corresponding piercing/bludgeoning(crushing?)/slashing is properly applied to each weapon.

I have greater doubts that my next suggestion will be implemented but I'm typing it nonetheless.

2. For any weapon type, make a unique item under that type that is end-game worthy. Somehow, by the end of the game a player can compare a dagger wielding character against a great sword wielding character and be satisfied with both builds. Balance, so to speak.
