I played a lot of both Midrange Hunter and Hybrid Hunter during this period, and I have to say I agree that Hybrid Hunter is the stronger deck. I never messed with any of the secret builds, I'm not particularly fond of those decks as they currently exist (or Hunter traps in general).
Warrior getting knocked down a few pegs also correlates with what I saw. With so much of ladder being Hunter it's very difficult to play any Warrior slower than Dragon Warrior.
I'm 42% with DW against Hunters, but it's so draw dependent, and while Hunter is getting stronger with the Kara cards, I don't see Iron Portal or Fool's Bane helping Warrior narrow that gap in any significant way.
Everyone was calling for FWA nerfs but the meta isn't very kind to FWA with cards such as Kindly Grandmother, Totem Golem, Argent Squire, Possessed Village, Mirror Image, Stoneclaw Totem and other FWA-resistant early drops, not to mention Acidic Swamp Ooze making its way into a lot of different lists lately.
If aggro shaman is strong against Hunter I might actually pick it up. I've never practiced that deck so I'm very hesitant to start playing something new this late in the season, but none of my current decks are performing better than 55-60% anyway, and most of 'em are closer to 50%.
