These creatures are usually underestimated and looked over. Taming these at early game can be a life-saver, as they can gather more meat and hide for you easier. In packs they are very dangerous. Dilos are good for body guards, hunting, carrying, and can be turrets encumbered and on aggressive lol
You can't ride them, you can't use ANY acccessories on them, they can't carry much, and they don't deal much damage. I wish ark could give them a meatpack or something, like how dodos have decimation bit and gathering bit.
