Played a game the other day with my "new" Imperial Battlecrusier. The fleets were almost perfectly matched in abilities, which made for a very annoying game. Not because it wasn't unbalanced, but because there were no differences in the fleet's capabilities and specialites to use/exploit/etc. But, it was still a good game.
The Rebels won, but only just. 1 hit remaining on the Nebulon B, and with enough losses between the 4 surving squadrons to only make-up one full squadron when combined.
