I think they should be stronger as tames. Not their stats but what if their bite attack would decrease the targets speed so a Morreallatops couldn't just run away and their torpor damage is to low I'd say. Please make Thorny Dragon viable.
Gathers wood fast and carries it at 1/5 weight stone is 1/2. Weak on the sides so if you really like this dino to patrol keep another dino with it to aid. Excellent at killing mantis to gathering organic polymer and chitin.
If you are going to tame one of these with no dinos, be sure to upgrade your movement speed and get tranqs. When you see it whip its tail forwards move to the right you will dodge the shots. This worked for me.
A good thing to do for a lot of creatures is build a cage out of door frames and ramps once the creature is in just shoot it with tranq arrows or darts but the creature has to be big enough to not walk through the door frame
I have 12 on platforms 4 pillars high scattered around my base. I have an issuse with dino spawns in the base. So they act as a long range needle launcher. Weigh down with sand because its weight isnt affected by the dragons buff. Set all to long range aggressive and u have a protected base. Add a few plant X for added assurance. I no longer have spawn problems. Found a ready to tame terror bird today too pretty neat.
