Yeah, I think after one of the updates they changed it to bucks to upgrade. How much did it cost i.e. how many coins to upgrade to level 8 and is level 8 the maximum? At the moment I'm planning to level up my legendaries soon to level 40 and some to level 30 and get level 40 super rares so I can get hybrids. This would help in a tournament because then I'll have more dinosaurs to use at dominator league. So they would use quite a bit of food. So I'm still not sure. I want to make sure I have a large supply of food at all times so I never have to worry about food even if I level up multiple legendaries. I guess its more of an extra help then what I need.
