I finally got a rare incubator through the battles. All 2606 common DNA went to a iguanadon and a lythronax. Why? Neither of those dino’s are any of the dino’s for the different arenas I’ve gotten to. I don’t need or want those dino’s DNA. It’s very frustrating with all the work I put in, especially since I’m not rich and don’t purchase things in this game. Would have been nice if at least some of the DNA went to a common dinosaur with a hybrid possibility. I don’t get it.
