I do object to the over-reliance on metagame % not only because it seeks to disparage subjective experience but because the raw data itself is corrupted by players' choice and attendance level. For instance, if I decide an afternoon nap would be preferable to playing a challenge, Oath of Druids suddenly has a 25-50% lower metagame representation. Who even knows what happens to the win rate. If two Shop players attend a wedding instead of a Vintage event, there is likewise a palpable decrease. Since these attendance variables happen all of the time, imagining that the results %'s prove whatever it is we might be tempted to believe is its probative value is absurd.
The metagame is as bad as it was last year, because of the refinement of Pitch Dredge. It's an outrageous blue deck whose hand is sculpted by a free Dack Fayden and whose Arabian Nights land draws ~18 cards instead of 1. While I always thought Cabal Therapy was over the line, I never hated playing against Dredge the way I do this year.
Paradoxical Outcome/Big Blue is not a horrible deck in and of itself--it's simply the single card Paradoxical Outcome that I and several others take issue with. There's no historical metric that would excuse that degree of one-sided card draw and self-replication (ie the Mind's Desire problem).
Shops has its issues, but they are far eclipsed by the Dredge deck and the illegal-power-level 4x namesake in PO. Getting rid of its free win-ball and then restricting Walking Ballista or Revoker should abate any lingering concerns.
I will write about this more in depth in the coming weeks. I have started an article to post here and without any intention of rushing it.
Either way, although we differ starkly on views of the format, I am thankful that your perspectives are stated eloquently. I hope that a fleshed out new theory adopting a "qualitative experience" perspective will help fill the vacuum that's been there for many years.
