Ok, here's the following situation. I am facing a Vasari Rebel opponent who is sharing my border. I am Vasari loyalist. This is a single player skirmish against the AI.
After losing an engagement with a major force and losing about half of my capital ship fleet, I had to stop a major incursion by this enemy, who brought a level 10 titan, a couple of capital ships, and a medium sized fleet. I have approximately 10 capital ships (about half are level 2 or lower, some are higher up to 8 or 9, and about half Kortul Devastators), a fully upgraded starbase with maximum weapons and armor, and I have a level 6 titan. I have also been adding a large supporting fleet consisting of mostly enforcers with some sentinels and some support cruisers. The enemy has only his titan, but because I have a phase jump inhibitor, he is not jumping. Instead, there's a stalemate where I can't kill him and he can't kill me. My ships don't gain experience, and he keeps regenerating the 4,000 or so hull points I knock him down almost instantly. Suggestions on how to take the titan down?
