My question here is: If you removed or 'nerfed' x7 Defenders, what powerhouse would immediately take their place?
Personally I've just found the action/token economy race quite tedious to keep up with. Always bound to happen the more and more upgrades and slots that appear, but it's definitely taken a bit of a shine off the game over the past year or so.
I guess that part of it is that it currently feels like there's X-Wing: The Dice Game and X-Wing: The Guaranteed Damage/Evade game, with the latter being the standard these days at events.
Maybe casual epic is the answer...
Reminds me of when I started magic back with the very basic 4th edition (power was all removed and very little was there in card economy), over the years new releases changed the game so much with how you could choose to win or take card advantage to new meanings. Each new expansion sees new winning decks in tournaments, follow up tournaments find counter-decks to those past winners and the 'meta' constantly changes and adapts to suit - I can only assume that X-Wing will do the same.
Perhaps if we're lucky a set of Title cards for the original ships will assist them in becoming a little more on par with the new releases.
Magic dealt with most of its problems by format system. We have standard, format in which you can only play most recent cards, modern, in which you play cards with 'new' layout and legacy, all the cards with some bans (i will not talk about vintage or limited here). And guess what, legacy is total cancer. I know some people like being killed in second turn, but not many. You just need to go full 'turn 0' and get all those OP cards (legacy is full of those, it's not whining or sth) and prepare counters for like, every deck possible. (Fortunetly you have a sideboard) In fact, for casual player, none of those formats is really accesible. Cheap modern deck is like, 300$. And your standard deck will lose all of its value in 2 years. But it's still a way to have many diffrent enviroments. We have only "legacy" way to play x-wing because of its nature. And legacy never changes. Never.
I like your post. System format would be the best way to balance without changing any card texts, and would have an effect for the rest of the life of this game. The easiest system format to implement imo would be competitive missions... which brings us back to this post:
