Again another flaw of this game which im sure you are aware but never seem to do something about is your zone spawns. Why is it that one zone is way better than others and one zone is filled with bad neglected dinos?? Should this be balanced in a way that distribution of dino recipes, specially good ones are not cluttered in one zone?? To highlight, zone 2 is the best zone while zone 4 and 1 are the worst. If your idea of balancing is prioritizing a zone and neglecting some, again get ready to lose more players. People will stop grinding if they know there is too little progress to gain.
Here’s a guide that some made because you just cant make and publish one.
