Losing battles with overwhelming odds
I can't seem to win the large space battles when the enemy comes en mass. Recently, I had 5 captial ships with a dozen cruisers and frigates. Hanger defenses abounded as well. The enemy came in with 3 captial ships and a large number of supporting cruisers and frigates w/fighter/bomber support. My captial ships outclassed the enemy by at least two levels. After losing my first capital ship, I phase jumped in my second task force which had 3 capital ships and a dozen more frigates, cruisers, fighters& bombers. These too fell to the enemy while I didn't put hardly a dent in the enemy capital ships.
I ended up retreating and rebuilding but they kept advancing on me. Ultimately, I lost 14 capital ships and all my cruisers/frigates to their force...while they lost 0 capital ships.
Ideas of what I am doing wrong? I had pretty strong weapons researched as well.
