Compies are not actually useless, thanks to their small size... They're excellent base defense dinos if you tend to build bigger bases with lots of walls and doors as I do. After breeding some for melee and health, I have a pretty solid family of lvl 280-300 compies in my base. They don't get in the way, and are set up like sentries on aggressive. They can even fit in between forges and other internal structures, and creating a few false rooms filled with compies is a good surprise for raiders.
On two occasions these things have saved my resources
First time, someone broke all the way into my forge room, where I have 6 compies stationed between the forges, with only the one furthest back on aggro, the others on neutral. The moment the one aggrod, they all ran out and while 2 died, they killed the raider and I was able to revive and replace my doors and throw out a cryopodded giga.
Second time, someone came to a split hallway and chose the room filled with compies... Rip lol.
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.
For practical uses that is. Compy’s are the housecats of ark. Tame one and set it on wander inside your house and you have endless companionship. It’s dumb, and really impractical seeing as you probably have tons of other games to keep you company, but it’s still nice to see a tiny little dinosaur run around your home.
