We limited squadrons to three per fleet of 250 points for speed of rounds.
In hindsight we should have said you must bring exactly 3, as all but 1 Imperial player brought zero :-)
Because otherwise people would not be able to bring 2 ISDs! (Although only few ISD's on the table had ECM's or Gunnery teams I think)
2 x ISD = MUCH spectacular table top fun :-)
