I would like and be willing to pay money for:
There are many other things I would pay money for:
Bags that hold stuff I am sick and tired of not stacking into bags, like Plainer Shards for example,
Potion and Scroll cases are a decent idea, even if they only work like the cookie jar, where you need to take the potion/scroll out if you want to use it.
The ability to turn "looted/normal armor" into "Cosmetic Armor" (This is overdue and is already done with many other games)
The ability to apply one weapons skin to another weapon: IE: Take one dwarf axe and apply it's cosmetic to another dwarf axe (This is long overdue and done with many other newer games)
