I dont know if devs already do this, but they should collect statistics of how many times some items are eaten/studied/gilded/crafted/built. Then they could look at things that are not used at all and buff them! (Or maybe nerf some things)
There is no point in adding new items if they are just going to end up being useless or then make the old items useless. Foods/gildings/curiosities/containers and all that.
Collecting feedback about balance from the players is difficult and time consuming and does not always yield good results. Not that many players want to tell that some curio is maybe unnecessarily good and things like that.
Setting up some means to collect simple statistics mentioned above does not seem that difficult. And using that data to adjust game balance does not sound that difficult either. The game is in alpha after all, re-balancing things should happen more often. Because things are not balanced.
Stuff like Völva's Wand are just waste of metal, it is an awful curiosity. Takes lot of space, is expensive to make, does not give that much lp.
