My thought is you have to use your Etherium somewhere. I don't really think of the payback ratio. By levelling up rift dragons, it reduces the time required to level up the next dragon or get the next habitat, etc. Of course, I've always been a little obsessive about levelling up dragons - all my regular park dragons (probably 500+ dragons) are at 20. I currently have 177 rift dragons @ 20 and 57 @ 19.
