Yawn-o-rama. What you mean is you either haven't given it a go properly, or you're incapable of flying a ship that doesn't do the work for you. Vulture/FAS get referred to as "no skill noob ships" in certain corners of the forums because their handling means they don't take any work to get good at battering NPCs in a RES with.
Take a week to use the Courier with some FA OFF manoeuvres. A lot of people that do give it a go say it outflies even the vulture. What it lacks is weapon punch, but can't have everything.
Usable missiles...there's a thought. I've typically used the courier as a power plant wrecker using either two pulses/canon or one fixed beam and two canons, but missiles might mean it can finally be efficient against NPC wings. Strip shields of smaller ships, vapourise the hull, move on.
Attacked by NPC wings is hard, you need to use hit and run tactics.
