When it comes to the actual utilitarian use these things are good for about three things scaring noobs on the beach as you roll up with 20 following behind you or, egg layers which produces kibble for the pelagornis. The last is a special attribute of all shoulder ridden dinos, all the weight the compy carries is reduce by 1/2 when shouldered.
I wish there was like an attachment like a camera or something attached to a tamed compy’s back. And you can control it and look around through the camera while using the compy to run around and look. I think that is a good way to scout a tribe I wish there was something like this in the game. The camera needs gasoline to be activated just needs to be put in the compy’s inventory.
