What if the next tank class is ACN?

[Bigcat9715]

Seeing that ACN can become healer/dps what if Acn can become a tank? Maybe call it something like Sentinel, but be more like a tank with a pet. Shiva would be Shield oath and Ramuh would be sword oath. Then the way the class would work is by the player holding the boss and sending their pet to go and pick up adds. This is just a idea i'm throwing out there seeing that ACN may get 3 more pets it would make since if they turn the class into a tank.
