Rework Needed to balance end game content

So far even on easy settings in coop we cant manage to afford to get to any upgrades past stone. The cost of ownership of the higer tier stuff just doesn’t warrant having them, you might as well just spam cheap hovells all over the map there is never enough wood to fuind the upgrades of the dwellings and the balisters. and you need the balisters. but its silly to have all this end game stuff but its just not cost effective having them we end up going to stage 24 / 25 with nothing above basic buildings deliberately. please balance the waves verses end game content, something needs to change either lower cost of ownershi[p for end game stuff of longer waves that are less brutal with bigger gaps maybe. anything to allow a chance to expand to enough to warrant getting end game builds. even the fire walls cost wood.
