If I play a game I want to be competitive with said game. To be competitive with X-Wing in any given meta will require that that I have access to the options that other players who have been playing as long.
I have played MTG, played Commander in fact and even legacy. I had to stop the because I got bored because in the end I could tell what could happen more often than naught.
This game is sustainable but I don't expect more than 2 waves a year. Any more and it may have issues.
I do expect half waves though like X-Wing Aces packs. Those will be nice.
