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.
These are INCREDIBLY useful tames to have in mobile, and here’s why:
In Raids; In mobile, we don’t have cryopods. Due to this, turret soaking becomes a problem, in that it’s difficult and takes time to get all tames you need to soak to the enemy base. These guys are very fast, very easy to tame, and are tanky health-sinks even at low levels; making them the PERFECT soakers in mobile. need more? Go get some balm and mejoberries, and you’ve got your replacement in under 12 minutes.
Used as a construction tool, they’re the same size as a bronto, meaning you can easily build tall structures & tree platform bases using his sheer height. He has a lot of weight as well, meaning if you have an enormous amount of metal walls/pillars/ what have you, he can hold it for you.
Used for transportation, the same is true; he has SO MUCH WEIGHT! And he’s very fast, with 10 seats in his saddle. If you need to move base, he’s your man.
These giants aren't as useless as you think. While they deal no damage, they can push dinos and players around. They also have 10 passenger seats, ideal for carrying a tribe. Diplos can be used as distractions, while you kill the attacker. Good luck out there.
Since these big teddy bears can't really defend themselves tame a couple of little birds mount the diplo whistle for group follow. Then turn thier group whistles off (so they don't leave) and put the follow (so the don't get in the way) and attack range better at high. They will then stay with the diplo at all times protecting it.
