Why now you need oil or coal to run the farmhouse? why not just wood?
On some Island there are no oil or coal to be farm, like my one, so I ether need to move base to new island to farm them by farmhouse and use those to power the other farmhouse, sail to other island to farm them and bring them back to my island to power the farmhouse, or make a lot of fire place to turn wood in to coal to power them, that is losing the purpose of the farmhouse, because rather doing them, it was quicker for me to farm resources by animal, so when they say going to reduce people to use animal less, this make people want to use animal to farm again
in PvP relocate to another island, farm from another island is quite difficult, because you will get a consistent threat of being attack
