Sand Piles: Implement a form of sand storage, sand piles. Acts as a stockpile, except its not called a stockpile. To collect sand from it you must select dig on it. Maybe make us actually build a "sand box" to fill, that would be neat.
Animal Destruction: Allow fleeing animals such as bears, boars, moose, and deer to break boats, rip apart dead bodies(destroy them), break stockpiles, construction signs, and roundpole fences.
-I feel that while its nice to be able to kill all of these animals early on with our wonderful abusive tactics, I would like to see them not be readily available early game until you are able to melee them or at least tank them while an archer shoots them. This would be a good step in that direction. This downside to this is that people might use animals to destroy others things more frequently. Only way to avoid this is to make sure animals path to a clear opening before destroying something while fleeing, or prevent them from destroying some claimed objects.
Remove Coal Abuse: Coals currently used to cook things to the highest percentage possible with bad fuel, and then finished with higher quality fuel, and its treated as if it was cooked only with the best coal. To fix this, make the percentage of something reset if allowed to burn out. People will bitch about this. I say, put the right amount of fuel in.
Nerf the Mirk: Mirkwoods outclass every other curio in the game and it feels a little ridiculous. Maybe half their experience cost and base LP. Still extremely efficient in terms of lp/hour, and it keeps the same rate of lp/experience.
Somethings Fishy: Animal crossing style shadows can be seen in rivers and lakes. If fished some sort of large fish may be caught. Another idea I had for this was that you could possibly dredge up a fish you must fight or an alligator? But gators would be better left for swamps so i'll leave this to others to discuss.
Polluted Seas: Add different types of hooks that reduce the chance for catching rubbish, or just make things that are dropped in water less likely to be caught.
I know these threads with multiple ideas don't usually do so well, but I didn't want to make a lot of different threads.
