What I don't want, is a few years from now after we have had a lot of more expansion for a common X-wing battle to be between a few Skipray Blastboats and E-Wings Facing off against TIE Defenders and Gunships. I don't care if the ships exist and show up from time to time, but if they make the ships I grew up with, and love like little else in fiction go away, I would be sad. It would deminsh the game from what I feel is its core.
I can appreciate this stance. But from a gameplay point of view — disregarding the source material for a moment — I hope we don't keep seeing squads dominated by ships from Wave 1 for years and years. The reason to keep playing this game, or any miniature game, beyond the first few months is to have fun with new experiences, which come from new ships, upgrade cards, etc.
I will be so bored with X-Wing if, in 2015, I'm still playing against squads full of X-Wings and TIE Fighters. If those ships are still relevant and being sprinkled in, that's fine. But I want new ships to come out that get used by lots of people. It'll keep the game fresh and fun.
So here's hoping for E-Wings fighting TIE Defenders. That would be interesting to see.
