Only pump melee and health when you get levels if you pump only health it may tank everything but it can't do anything else and if you pump damage and health you can kill everything I've even kill a level 65 alpha raptor with my level 112 turtle.
First dino I ever tamed and bred. In my opinion its a slow breeder. But hell of a defender. Its just a good tame all around especially due to the fact its 10x better then a trike (in defense) and the saddle is relatively easy to unlock. Plus its got a cool swimming animation.
