Re: Things to replace the titan...
I wouldn't mind an Executor map. If I had my way, the ship would be static and cover the entire map (in other words, it'd be the "ground" of the map. Rebels would start over it in the south and have to make their way to the bridge tower in the north, taking out the ship's bridge to win. Both sides would have fighters, and the Empire would of course have the turrets scattered throughout the "city" surface of the Executor. In other words, it'd be a mix of Battle of Britain and GC Death Star.
As for the thread idea, a better title would be "Things to replace the titan mode" .
