I too am having difficulty playing on Normal speed. Granted, I have played 4X for about a year now.. Does anyone play on Blitz? How do you defend against 20 guardians rushing you?
That being said, 4X is still available so I'm not complaining about that. It does not help that I feel like a total noob playing, since I have no idea of how my fleet do against an AI fleet. Will have to get some more experience under the new system.
