Dinosaur Growth with Time
The growth system is extremely slow, it's almost as bad as The Isle (6hrs to grow a tier 5 dino). I believe growth for a single dinosaur should never exceed two hours. Many people don't have the time to spend 6hrs growing a dinosaur in one go. If people think this is unfair for being under two hours then have the dino start off from the beginning of the life stage but still have the skins and abilities saved.
