Don't underestimate this dino's usefulness. It may not do damage but it's knock back is very useful for holding off raiders. If your base is near a cliff you can knock players and dinos off it. Another thing is that diplos actually do trample damage. This means that it can kill small creatures like bugs, dodos, and compies by walking in them. In addition there is no level requisite to tame it, so it colud be the first dino you tame.
I would recommend one for player vs player gameplay because these guys can tank hits like it's nothing. these guys are very useful for travel to but maybe use for a mobile base for maybe taming in single player. I would put health, weight, food , and speed mostly. I hope this is useful for you ❤
