As title. I think friendly battle is a really great chance for us to experiment new dino and new team combination as everything would be on the same level.
However, it’s just too annoying to change our team in the collection page, then start a battle, and have to change it back to our normal team afterwards. It even adds the risk that we forgot to change it back and costs us arena trophies.
If we can choose our team from the collection page everytime a friendly battle start (or make it an option - use standard team or make a new team) I think it would encourage players to try out different combination as well as making it more fun for us as we can use those low level dinos to examine their full potential much more easily.
