Don’t let anyone tell you the diplodocus is completely useless. I’ve found a VERY viable use for it (especially in aberration)
The diplo may not be able to defend itself however its pretty dang fast,, it also has a crap ton of weight. So I use my diplo for metal runs. On the island I used it as an argument of sorts instead of carrying an anky with an argy (I had just started at the time) I tamed a diplo and used it to carry all my metal to and from base. And because the diplo is really fast it made the journey way less slower than it would’ve been. I now use my diplo in aberration as a permanent argy, except I gather the metal with my anky and cryopod it with all the metal in my diplo
I got an idea if the tamed diplodocus can attack.So it is like an upgrade for the saddle (that might make it cost more) that adds sharp spikes on its head so when it pushes enemies not only the get knockback they will also get hurt which means we can level up the attack of the diplo.Thats just my idea and yes I think the do deserve a tail whip attack cause they really need a defence in the wild man....
Everyone saying the Diplo needs a tail whip attack and platform saddle, seriously if you want that get a bronto, the Diplo has its purpose and so does the bronto, making one into the other makes one redundant and totally useless. Brontos are attackers and portable bases, diplos are a hybrid of speed and capacity, no one would complain about a gallimimus that can carry eleven people and still have space to spare for three tonnes of cargo, but they do complain about a Diplo which is essentially that in terms of functionality.
So if you wanna passive tame I found a sweet spot between its front legs in which it will be stuck trying to push you but can not. It takes a bit to find it but once you do just get a bunch of taming good and get yourself a quick transport Dino.
