14/20 of my last ranked opponents around rank 14 have been mage, priest, or paladin.
I guess the only option to be consistent here is bite the bullet and go back to old jade druid? Is there some sort of optimal accepted jade druid deck? I've tried to get Aya via drop but failed and still can't craft her.
OK, check this out. Those stats I mentioned? Originally, I looked at my most recent 10 ranked games. 7/10 mage/priest/paladin.
I looked back further for better data. 14/20 mage/priest/paladin, exactly the same ratio. I immediately changed to jade druid, same rank, back to queue. It's not a different time so it should be the same sort of people.
Want to guess what my ratio was for the next 10 ranked games? All in a row, no breaks, only 2/10 games were mage/priest/paladin. The odds of going 7/10, 7/10, and then 2/10 the instant I switch classes seems super weird to me (but obviously possible, as with anything random in the world). Of course I'd need much more data, but I really am starting to suspect your class and/or class stats may have a small effect on matchmaking.
