[SW] Why does the Clone Army stop using the ball turrets on their gunships?

Throughout the clone wars (at least the tv show) they seem to have stopped using them, except for when they return to Geonosis.

Later variants of the LAAT dropped the ball turrets in favor of a larger pressurized door that enabled the craft to operate in space as well as atmosphere.  
They lost some firepower, but gained the ability to deploy from orbit rather than needing to be ferried down to the surface by a transport craft.
