Ok, so unique cards count only for your squad ? If you have Luke Skywalker, your opponent can also use Luke Skywalker ?
Ah, sorry, I misunderstood you - yeah, unique cards are only unique per squad. You don't necessarily know what your opponent will field while building your squad, so you can't take their build into account, and there are no rules for resolving uniqueness conflicts between the sides. Two cloned Luke Skywalker can fight each other.
Yeah, it doesn't say it on the card, but one person is fielding Luke, and the other is fielding Luuke. And both have visions in their head of an old man saying, "You will kill Luke Skywalker!!!!!"
True, this unique bit sort of throws your immersion, and that's why I think the game should be restricted to Rebels vs Imperials. Then you'd never have this issue because there are currently no pilots on both teams, and the Imperials currently cannot use astromechs (right?). I don't have a problem with squad leader since that's a generic type of unique: each squad should get a squad leader, but no squad should have more than one.
