So yeah, Salt.
Why was it ever nerfed down to 5%?
Salt nodes are pretty rare and you get 2 salt per week, that's 10% at base quality.
Meanwhile i can say hello to a tree 3 grids away from the questgiver and he reduces hunger by 30%. All within 10 minutes.
If anything, salt should be buffed, so far all the special nodes are underwhelming as hell and there doesn't seem to be any point anymore. No one in my village even bothers to check any nodes that aren't literally on our doorstep anymore, because why would you walk 30 minutes for the CHANCE to get salt if you could just do a bunch of quests in the same time.
