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.
When you first spawn in but u see on of these bad bois follow the steps b3llow to survive
1.beg for mercy
3.jump off the nearby cliff to escape the dragon
4.hit the up arrow if you think wildcard should make these things fly
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.
If you have a wyvern or argy, easiest way I found to tame is to set up a taming pen, 2x4 with single door frames on the first level, walls on the second(stone), with a Dino gate on one end. Go pick up your dragon of choice and drop it in! Super easy and quick.
