Seriously, this spawn mecanic is tiryng and unfair for eveybody. I myself prefer the old spawn mechanic where i can find all everywhere. I had tons of dimetrodon dna and other dinos like epic anky or ouranosaurus, i saw only a few wild ones since july. Yes i go out another areas for hours and i feel im losing my time and only got tired, meanwhile local zone of dimetrodon guys are flooded whit they. Im flooded whit monoloohosaurus and other myself local dinos, meanwhile other people rarely can create a monostegotops i can have it at 27 if i had all the setegos i need( atm at 25 and half whit 1000 mono dna).
You need rotate at least each 2, 3 weeks the zones or make all rares global spawn. I could have magnapyrytor and a triostronix at lvl 25 if i had all the dimetrodons i need, i drive to his local area milles far and rarely get 1,2 at day whit luck.
