I too like to play with combined arms tactics (like Gozra). So although beams are the weapons of choice for main combat, I also find the missiles can be a great help to.
I find it frustrating sometimes to send fighters after a well PDC protected ships only to have their numbers cut down quite a bit before they reach their target.

(Fighters are an integral part of my combat tactics.) So that's where some missile ships come in. They'll basically launch some missiles at a time to provide cover for fighters, so that my fighters that are equipped with rocket packs and beams can actually get at the target. Most times I get acceptable losses in my fighter squadrons, which shows that missiles shouldn't be dismissed too quickly.
