1. Totem decay from abandoned tribes (my #1 and I wish this could be made a priority)
2. Ability to open pre-built structures like tents and huts the way you do bins, it doesn't take long to have a mess of bins scattered everywhere and it would give these types of buildings a better purpose. We all know that walking around inside these pre-built structures is pointless, the larger the structure the more it should be able to hold.
3. Item decay from items not inside a building or covered area.
4. Finish the Market system
5. Archery
