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!
If you use it’s kick attack and time it well then it’s possible to kill lots of stuff without taking any damage. Another thing is that their kick attack doesn’t hit in front of them. It also hits around their sides, which is useful when fighting hordes of creatures. However it’s damage is pretty low so you probably shouldn’t use it for combat.
Had one of these in a multi server, named him Steve Irwin. One of the best transport tames ingame period, got around 30 levels because of him. I’ve killed rexes and broncos with this thing. Knockback is amazing, and can easily run away from a fight if things go wrong. Sadly, game crashed in a cave and he passed away. Rest In Peace, Steve Irwin.
