At first they are really scary and really op let's be real. But once you find out you can easily knock one out with about 30-50 tranq arrows. They stop being so scary. Easiest way is probably to craft 2 big bear traps place them next to each other lure it into them and then just knock it out. If you can't craft those yet. Then I recommend trying to get on a Big o rock that it can't climb and just shoot it from there. They take a long time to tame unless you have a soothing balm.
