When I first stared using TAC fighters (yes more than one
) I was using the ground support option... But i simply found like all other 'artillery' mode weapons to simply be too inaccurate to be effective :/
Firestorm bombs are simply fantastic however even when those warrior bugs are packed together as tight as possible once the thing starts scattering youll be lucky if you hit 2 or 3 of them in the blast.
On the otherhand with a Ground Attack Missile you can ssure your hitting exactly where you want to hit to optimize the casualties... and even avoid your own models with pin point accuracy.
I also find the prospect of firing a nuke without knowing it will hit exactly where you want it somewhat idiotic
Needless to say Ive switched over to Tactical and never looked back.
