Perhaps the most enjoyable part of the game used to be collecting dna. We would often plan family days out just to do this, and the rewards from doing so were worth it.
A new and stronger Dino would enhance the team.
Levelling an existing Dino would make the team stronger and thus, it would lead to more arena trophies and so on.
Now we have, as the original post states, a situation where levelling up creates an issue where you get penalised for having a better team. The matchmaking currently is such a mess so there’s no point in levelling up unless you are prepared to go on a losing streak.
We now find that collecting dna is pointless from a personal perspective, but continue to do it for the alliance. We store it in the hope that it will worth something in the future. And none of us play in the arena for anything other than a daily incubator.
