This idea sounds really bad. This is how you tick off the players that collect dinos for fun in the game. If you switched out old dinos for new ones, and players were breeding the ones that got taken away, they would be TICKED OFF if they lost them. This concept works for games like Fortnite because you only have the same guns for ONE session, and in the next you start from scratch again. That isn't the case on Ark.
I am in favor of more TLC patches for dinos. We definitely don't need that many new dinos in the game, since many that we have now are useless because there is too much variety.
