(1) How about if the Survival Tool could only harvest ore from surface rocks, not deposits? I tried this on my most recent play-through and it worked out okay. It forced me to be out in the world more. (2) How about if the Survival Tool could only harvest wood from smaller trees? That is, not the trees that have large trunks. I've not tried this, but it doesn't seem like a major complication. Perhaps better, greatly increase the amount of damage the large trees can take. This would keep drones from disintegrating them with two shots from their minigun.
