You're forgetting that when you fly a capship, it's not just 'point and shoot', ever, really. Especially on a Terran warship, you can engage multiple targets concurrently by flying the ship correctly, so each cannon battery has a clean arc of fire to its respective targets. Then there's the matter of rolling the ship and maneuvering it to keep hostile fighters in the AAA fire pockets of the vessel.
Then there's also correct disposal of the fighter escort, which can make your life much easier.
I don't think flying any kind of capital ship would be 'boring', so to speak.
