Still haven't got my Burnoose yet, BUT I've been keeping closer track of who spawns where...

These are all the spawn points, and the ones that I have seen Named mobs Spawn at. The letters are the first letter of the named I've got to spawn there. This isn't complete as I've left the named that spawn inside tents up and killed all the wandering ones. I'm pretty sure that the general spawn time is 6:36, really fast respawn, really low spawn rate for named. the one Campfire spawn point closest to the rock I timed to 1:13:39, though I might have been a few seconds off. Seems that if you keep the named up in the tents you really increase Zed's chances at the campfire. Hope this helps, and hope I get mine soon!
