My Mortem Rex hit level 30 last week; any additional DNA earned will now be useless. Although I’m still helping my alliance members with Mortem Rex raids, I can see that many players will decide not to bother with raids anymore once their apex is maxed. Since the boost shuffle it has already become more difficult to organize raids and this will make it worse.
So why not award generic apex DNA once a certain apex dino has reached level 30? This would be similar to rare candy in Pokémon Go, which can be exchanged for any pokémon candy. This way I could have used the 15 Mortem Rex DNA I earned today for Gorgotrebax (or any other apex boss) instead, definitely a motivating factor to participate in all apex raids.
As more and more players max Mortem Rex (and later the other apexes) it will become increasingly difficult to find Mortem Rex raid teams. Awarding generic apex DNA once an apex creature has reached level 30 would be a solution to this problem.
