Go play X-wing sometime...Perhaps it's just a reflection of the reality. The Empire always outnumbered the Rebels. Really Armada is depicting a relatively rare scenario where a Rebel force actually goes toe-to-toe with an Imperial force. The objectives help "justify" the Rebel presence better to some extent.
But anyway, yes, the Rebels are the virtuous force. Ergo they are fewer. Thus more people are Imperial players. Because Rebel players are virtuous people. And therefore fewer....
YT's everywhere :/
which is part of the reason why we're playing Armada
Until Rogues and Villians?
