Ok just a suggestion here and while I think it is a good one I am simply putting it here so others can comment and you guys at SocialPoint can at least hear the idea.
I find myself with an excess amount of firesaur cells as a for instance. Now just letting them sit there and do nothing serves no purpose. How about a way in the cell lab to upgrade them to the next tier. So Common cells become uncommon, uncommon becomes rare and so on and so forth. Or a truly epic amount of them can be made into elementium.
An exchange rate around 50 of the lower quality for say 5 or 10 of the next grade up.
For the elementium say 100 for 5 elementium.
Also let us pick from a couple of monsters for the upgrade. Usually nonbreedables for the higher tiers. Just a thought guys.
