I've been trying to think about what has changed in X-wing lately, and have a possible theory.
Prior to Wave 4, list building and meta analysis was mostly proactive, rather than reactive. That is, you built to the ships that were good, and strategy that worked, but there were very few things you had to specifically counter, and those that you did rarely required anything specific. There were far more broad guidelines than specific counters. And even in cases where there were things you had to be aware of - ion threat, for example - the reaction came in the game rather than in the list-building stage. At the absolute worst the things you had prepare against were very general - "swarm" and "high-HP list".
But with the advent of Phantoms especially, and the follow-on development of Fat Han/Chewie, and now the insanity that is a hypermobile HLC Turret that ignores asteroids while getting 3 actions a turn, that's no longer reasonable. Our meta has become reactive. There's now a good long list of ships that in isolation look to be perfectly good, but are useless if they can't beat X or Y. Our reactions have reached the list-building phase.
This is, IMHO, the source of a lot of the recent consternation. It's a new set of constraints which occur at a different level than we're used to, and it's seriously compresses the meta.
More importantly, it's pushed a lot of the strategy of the game into list-building rather than in-game strategy. Not comprehensively, honestly, but most of the discussions (and flaming) over how to deal with Fat Han have to do with list-building options - bring more guns, use Outmaneuver, etc. Dash is shaping up to be even worse - I consider a classic Garven/Dutch XXXY list, and have a hard time imagining how you'd pin him down. I look at 60 points of Dash and figure it could destroy what used to be a solid 100-point list.
This worries me, and I think this is a bad thing for the game. X-wing provides a great play experience because the game is good. The more we have "Well, there's no point in playing this matchup" matchups which are decided at the list-building phase, the worse the game is going to be.
While I'm sure the usual suspects will have the usual responses, I'm curious what the rest of the community thinks. Has anyone else felt this shift?
