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!

TLC patch coming March 2018 to add a carry weight buff, reduced falling damage, "Kick" attack, and the ability to carry baby dinos and small creatures in its pouch. Like for people to see!

Great to have tamed in harsh environments (snow, scorched earth, etc) as the pouch gives protection from the elements.

Can jump over behemoth gates if on a rock and can easily jump over dinosaur gates. That is very useful when it comes to raids if you upgrade your procoptodon in health enough. -rick

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.
