Level of the Dino, or more importantly, the melee of the Dino, has no effect on the amount of melee you get per mutation. If you get 11.6 melee per mutation for a level 1 you’re going to get 11.6 melee per mutation for any level. If you have a dino with a higher melee you’re still going to get the same thing because it goes by point total. Imprinting baby Dino’s adds a percentage based boost based off of the stats. Maybe that’s what you’re thinking about.
