The one thing that gives me pause is that this may be yet another thing that is countered best by bombers... I DO NOT want to see that...
It would probalby work if it were just a double sized capital ship, say 2x hull, 2x shield, and 3x firepower. You could still focus fire that to death with a large fleet.
I wonder if they might consider implementing one of my older ideas. Reduce the amount of experience needed for a capital ship to level up and increase the max number of levels. That way a capital ship might eventually be able to become Titan-like.
As long as Rebellion learns from the mistakes made in Diplomacy, it should be good. I just hope they fix the mistakes in Diplomacy in the mean time.
Balancing all of these additions is going to be daunting. It's gonna need months of Beta-testing.
I also really hope that they will focus on releasing a high-quality product--almost no minidumps or desyncs, elimination of lag in online multiplayer, less CPU and RAM intensive, no Mesh Errors, etc.
