Use bolas to stop these if you or your Dino is slowed by their attack. You can also run in water for safety because these cannot attack in water. 50% reduced weight for basically every important resource so these make great pack mules. These can climb across zip lines, press jump while looking at one (crosshaie should come up). These also jump high vertically unlike most mammals that usually jump forward, and these take extremely reduced fall damage! Great all around dinos with many uses!
With these ravagers you can ride on zip-line anchors, making this creature unique. You can use this feature to your advantage so you can steal Rock drake eggs if you don’t have one, although if you don’t have stew it will die of radiation. They come in packs of usually for me, four, and can gash targets making them very effective at taking out high health stegosauruses when they are soaking auto turret rounds. Make sure to mass breed health and melee for effective ravagers.
Taming one will make a lot of stuff easier for you. Some items like metal will only count half their weight in its inventory. And they have quite a lot of weight.
You can even walk on all the slacklines, natural ones or even the ones you can shoot with your crossbow. And you can even walk them up, hang upside down and turn around on it. Made farming metal for me much easier :)
