damn i really like this meta. current iterations of aggro shaman are much more midrange than they used to be, and even though their core set of cards are busted, at least you have more time to respond to them now.
yogg swinging games is dumb, but most of the time it's like a pretty good board clear that might give you a secret or two. not justifying it cuz it is dumb and it shouldn't have been printed, but at least in practice it's usually ok.
i don't mind losing to a worse player when they aren't playing outright terribly. hearthstone is a card game, and there is inherent rng in every card game (draw order at least) and matchup in most of them. i mind feeling like i never had a chance, like when a discardlock high rolls or a tempo mage nutdraws.
The first part of your post is a little funny considering that VS data reaper report puts mid-range shaman at a 56% win rate. That's higher than patron. Also, according to their data, there is no bad match-up aside from the mirror. You can't react to shaman, they can always react to you.
