Earthshaker Class?

I have an idea for a class that can shake the ground with their full body weight, causing huge fissures and landslides in front of nearby opponents.

Pros: Long-range attacks involving hip smashes that shake up the enemy.
Cons: Possibility of getting stuck in their own fissures or falling through the floor.

And get this: The fatter the person is, the stronger the magnitude of the ground stomps/smashes. No magic or weapons required.

Interesting idea, I’ll keep that in mind.
