In raids the kaprosuchus can be very powerful at picking off snipers at a high point with its leaping attack or even lone survivors just spawning in. It is pretty fast in land and water which could allow for deep sea raids in caves.
The kaprosuchus can use its leap underwater as well as on land to grab unsuspecting creatures that are smaller than itself. Overall it's a good creature to us whilst trying to pick off unsuspecting players or animals as well as gathering food for your tribe.
I think the devs should add a command for singleplayers that makes it possible for the Kapro to grab creatures on it‘s own without attacking them, so the player can stand in front of him to knock the dinosaur out (as a command like you can activiate turret mode with the chalicotherium)
These tames are good to defend your base leave several on the setting to attack anyone attacking your base because they can jump and dismount attacker I left some on the roof and they picked attackers off there flying tames and my turrets did the rest
