I think this shouldn’t be a major feature but just like we can tap the screen to make them roar, a little detail of being able to pet them would be cute. If someone doesn’t like it, they can just not use it, lol
The thing is, when you bring your dinosaurs for battle, they win a match for you and roar in victory, you end up being fond of them. They become your pets, your squad, your companions somehow. That’s why people have been asking for an option to name them for ages. This would have happened even before Jurassic World came out, but now, after seeing that sweet relationship between Owen and Blue, we like it even more, we can’t help but to find it cute -some of us, anyhow- and feel some kind of attachment to our dinos. Every time my tarbo won a match for me I’d be like YASSSSSS THAT’S MY BEAUTIFUL GIRL.
So really, a bit of bonding on the side with an option to pet and feed them wouldn’t be out of place at all. After all, we are supposed to be the DPG, aren’t we?? We are supposed to protect dinosaurs and care about them. I’m all in on this as long as it’s something on the side, as the OP said.
