Which ones do you think would make the game unrealistically easy?

There are some things that need some work. There are some mechanics I don't like. There are some things that have never made even fictional game sense (like the onions or the special rocks needed to make a forge).

The food = hpts mechanic never made any sense, any more than the vitamin implementation in Atlas made sense (since you could sail across a full map in less than 40 hours). The vast amount of excess loot in this game has always been unfinished business, as have the barking deer.

Let me add to that the need to put down a crafting table every 20 feet to build/repair anything... including roads, and the simplicity of the hoe that does not allow for better levelling of the ground.
