All I can think of is how awesome you could make missions if there was an Assault Gunboat.
Convoy Rescue.
Hyperspace in and disrupt an attack on a convoy by X-Wings and Y-Wings.
Dont need gunboats if you have a gozanti. Deploy within range 1 of the transport, save the freighters before he rebels kill them.
It's for those of us who want to relive our days playing TIE Fighter on PC.
*edit* and some of use don't want to have to use the Gozanti every mission.
