The gunships are lacking a heavier fast reasponse "thing" so what they need is the new ~spiker~
The design would be a cross between the reverent and an angry roomba- it weapon would be to shoot physical saw blades and do damage though collision, this also the saws to nicely bounce around as they hit stuff. It would be slightly larger then the harpy and have a ~5 second cooldown.
Damage would be done; again, by COLLISION damage only.
The system would work like this: the second the saw touches something the game checks if it would die, if yes the saw loses only a little speed but continues on it trajectory. If the saw will not kill the target, then the saw does its damage and bounces off in a random direction losing about half speed. This would give the gunships a well needed fast response to heaver units and/or a swarm as the saw could pass though and kill multiple glaives.
