Here are some ideas.
-Scaling NPCs, both enemies and non-party allies alike. And not just the generic "scale to PC level" but other options such as "scale to PC level + x" or "scale to PC level but max out at level 5".

-An option to make some skills exclusive to certain classes, such as the 2-handed skill not being available to the Mage class. So essentially creating specialised classes, instead of the current system where everyone can level up in any skill, which totally fine, but the option to create normally RPG specialised classes would be nice.

-An online option so several people can populate a map with items, sort of like a Google-drive document that several people can edit at the same time.
