Since everyone always wants to play dinos, and the teams are never balanced unless enforced, why not add dinos to the humans team?

A small speedy Ceratopsia type dino that can be pounced by raptors, and eaten by rex, etc.

A Pachycephalosaurus perhaps being a little smaller and faster than Dino team equivalent, can be pounced by raptors but only for half health, and can be eaten by rex, etc.

A limit of 1 or 2 Ankylosaurus to serve as the Humans "Tank", and can be ridden by 1 human to shoot from and cannot be pounced on and cannot be eaten by rex, etc.
