If anything the prospect of getting hit by cloaked enemies pushes me in the other direction; from canon, gimballed weapons are stored inside the hull, presumably lest someone defang you with your shields down, and require time for a physical mechanism to open the doors and extend the weapon out.Yes, but this nessicitates we build more smaller ships and fewer larger ships. We would be forced to keep ships small to maintain maneuverability and then get hit a second time with the small ship stick as we need more and more expensive phasors for large ships.
Meanwhile if we go with gimballed phasors we can get away from small ships entirely and build cruisers and battlecruisers.
And basically ALL of our future enemies are likely to employ cloaks. Being able to shoot backwards seems really useful.
Not to mention, again, that once in combat they're a great dangly bit for someone to try to shoot off.
Embedded, focused emitters will have faster response times in whatever firing arc they possess and more durability under fire.
Large ships can afford to mount them to cover all arcs, and maneuverability will be the order of the day for escorts up through light cruisers, as it was this past time.
