I find it useful if you pump nothing but weight and then harvest metal with it, just put yourself in the pouch and have a friend walk up to metal nodes, then you can harvest metal without even leaving the pouch!
I pump pure speed on mine. Always. Nothing better than a Roo with 200+ speed.
These guys are great at gathering thatch. Maybe not as good as a Bronto or a deer, but they are so fun. I use any excuse to take one of mine out to get some thatch.
They make the same bite noise as a parasaur, which is disturbing, but hopping around from tree to tree is undeniably fun.
Now one of the most important dinos for rasing babies! Have them mate boosted and you can get extra imprints and reduced food consumption! Baby goes in its pouch! Be aware its kinda bugged to do it...ark life...
Put a lystro in its pouch. Have a tribe mate ride it and follow to quickly level it while hunting on your big Dino's. If you're solo just set it to follow on an ample distance for solely leveling the hunter.
These are amazing early game mounts that will always remain useful. Level up carry weight and you can use it not only for metal runs but chop trees while on it's back. It's also amazing for combat as it's knock back is decent but more importantly it allows for a great ranged weapon mount with it's turn radius, speed and jump to avoid close encounters. For the rare flowers if on scorched Earth then tame a Morello and gather the purple plants with it. On any other map raid beaver dams!
