I'm new to Armada (also play X-wing) and I just picked up my own core set along with a 2nd movement tool and dice pack. I am wanting to primarily play Imperials but will likely get a few other Rebel bits just to make for interesting small introductory games. Since we're now looking at Wave 6, a lot of the guides for beginners seam a bit long-in-the-tooth.
What do you consider are must-haves? Anything that would be a "skip the ship, buy the card"?
Do you consider the Rouges and Villains squadron pack a must have?
Is the Corellian Campaign a must get? It looks interesting but I am wondering what sort of priority purchase it should be; get it soon, or wait until I've bulked out my fleet to the 400pt mark?
