Alright, I'll admit it, I didn't read all of the 15 pages of discussion on the Rieekan topic, so maybe this was mentioned already.
I have been thinking about a unique squadron limit for awhile, and actually I didn't first think of it as counter to Rieekan, but from more of a lore standpoint. I love the squadron aspect of the game, those tiny ships are the best. And to me that's the epitome of Star Wars, little tiny ships making a big different on a huge battle.
That being said, I get a little bored when most of the squadrons showing up are unique squadrons. It's a big galaxy, and yet Norra, Wedge, Biggs, Luke, and Jan, plus maybe Gold Squadron all show up to the same battles! That's not to mention Rhymer, Zertik, Darth Vader, Saber, Jendon and Maarek all show up to one as well.
So maybe it would be nice to have a limit on how many Uniques squads you can have in a fleet. They are suppose to be unique after all, and leaders of the much more numerous not-so-famous or not-so-lucky pilots.
My thought would be maybe limit unique squadrons to half your allowed squadron total. I think this would also help Rieekan Ace lists from being quite so dominate, and maybe squadron lists in general that start making crazy synergies.
That's my thought anyways.
