Please don't do this. This kibble change will single handedly eliminate 80% of the dino content from the game. The old tree just needed a little tweaking.
Think about it. The only interaction most people have with most of the dino content is to tame them for kibble reasons. Scorpions would never be tamed if they were not the kibble for rex. That goes for a lot of dinos...Gali, terror birds, pegomastix, and on and on.
This kibble change is not an improvement, it's a gutting of the game and a bypassing of a lot of the dino content that was added.
