Great for Large Cargo Trips. Simply ONLY level up Weight, movement speed, and stamina for a lean, mean, fast collecting machine! Collect huge amounts of metal, stone, crystal and obsidian in a quick trip!
I had one who was a beast. Level 55 but got her to 140 when I encountered a rex. After a short runaway I managed to kill the rex. Then on the way back to base a bear killed us all. - Note to self... Avoid bears
I use my paracer as my cargo transport dino for short to mid distance. I use it to go to the redwood nearby and gather MASSIVE amounts of metal. Just hop off, get the metal, load up the paracer, then get back home. They can defend themselves quite effectively
