I would think there are quite a few users like myself who enjoy hunting but have cut way back on our hunting time. The ‘more active’ hunters have several hundred thousand of pretty much every creature available to hunt. I have many common, rare and epic to level 20 or above with max storage showing and enough to get them to level 30… with DNA to spare. Quite a few are at Max Max storage. Why would I ever dart another creature I have no use for?
Without hunting access to new creatures there is little reason to go out and spend any time hunting. Without any use for the DNA I already have an abundance of, why would I dart more of it?
