When the game comes out it will still be in alpha, so why not.
Basically, my idea on preventing alt spam and forcing using mains is pretty simple but needs some polishing - In order to eat a farmed item, you need a farming proficiency that is required to farm it in the first place. Cooked - cooking (idk how this would work though considering cooked items also take oven quality into consideration), and same with curios. Basically what this does is makes raising a character from 0 to hero almost as hard as the very first time you raise your main.
The biggest fault I can see in this is it removes all "forced" teamwork that was there with personal beliefs, in other words you can do everything by yourself. Any ideas on top of this? Critique?
edit: oh and it would also probably fuck up trade
