Well this has certainly been a discussion, thank's for your post's info and suggestion's. I have also noticed once I have completed the daily hunting task's for Cripps the spawn rate improves. So in conclusion I have decided this is deliberate by R*, example I joined a possee of 30 & 40 Lvl players to do long distance trade run's wih them, one was a bit short of the 100 so they went hunting and they found very litte to shoot. so I tried an experiment I left the possee jumped server and with in a minute got a message from possee leader saying animal's in abundence. i am Lvl 264, so it apper's R* are nerfing it for higher Lvl player's. Nuff said.
