In my opinion, these guys are the best, go on, say i am weird.
First, they are very easy to tame, all you need is a few spoiled meats and a bola, tranq arrows or even slingshots will do.
Second, after they are tamed, they are super useful, you can use them for cheap creature knock-outs, plus, if you tamed one in a cave, then use it for exploration, nothing in the cave can pick on you, making it easy to get to the artifacts.
Third, they are super easy to care for, they eat spoiled meat as well, so if a stack of meat spoils in its inventory, it will still eat them.
They have decent speed, stamina and melee damage, and can cross over tough terrain that most dinosaurs can’t.
I don't know why the guy saying they're not affected by Bolas is at the top. I just hit a level 5 wild in the mountain area with a bola right in the legs and it froze in place perfectly, no issues. BOLAS WORK, BUT YOU HAVE TO HIT THE LEGS, THE THIN SKITTERY EASY TO MISS LEGS.
