instead of more legendary/unique items, i would like to see several grades in existing items. in my opinion, the gear progression is way too fast. let me give an example:
1. grade: broken sword
2. grade: rusty sword
3. grade: used sword
4. grade: militia/regular
5. grade: military/regular
6. grade: masterpiece/legendary/unique
graphical differences could be very minor, if at all. i think, this would give a lot more depth for not that much more work in comparison to completely new items.
