Ludia’s idea on creating super hybrid dinos is to use one hybrid, and as second, a normal dino (not hybrid).
I think would be interesting to be able to create super hybrid dinos with 2 hybrids. That would expand a lot the variety of new dinos and also give to the players more challenge to get those super hybrids. Imagine to get X super hybrid, we need 2 legendary hybrids… Amazing challenge, yeaah?
