These things are great to have in the Alpha Rockwell fight in a support role. They are extremely tanky, fast when they are submerged and swimming through the ground, and you can shoot from their back without dismounting. The combination of their Blinding Debris attack (prevents target from attacking for 5 seconds) and their whirlpool immobilizing and damaging reapers and nameless in a wide radius that spans the whole ramp to the Rockwell boss platform makes them extremely effective at mitigating waves of reapers and nameless and keeping your friends on the boss platform safe.
An imprinted faso with a capped saddle will be fine at 20k+ hp, and extra points dropped into stamina to give your whirlpool a longer duration and plenty of extra juice to swim around the arena to shotgun down stubborn tentacles. Bring a light pet, the best pump shotty/Flak armor you have, healing brews, and Calien soup.

Their sandstorm grounds flyers. In caves with high level flyers like Onyc and Seekers these guys makes a great frontline. Bury in the ground, have your Tribemate shoot the mobs to have them fly over your trap, and Immobilise them all while he moves in for easy ground kills. Love this big guy. Wish he had on the spot rotation though, he can get flanked easily.
Suggestion: Faso is able to un-smelt iron by crunching it up. It would have a button similar to the "seed fruits" that the iguanadon has. It would be useful for crafting things that require raw metal, or maybe it would be a decent way to sort metal out. It could also have a special item called "fasolasuchus plates" that would be used on the saddle. The saddle could provide protection from sandstorm, and give the rider a temperature buff.
