So all 9 classes have at least one deck with a >50% winrate.
The lowest one - rush warrior - was a good deck last expansion, so we know it isn’t just some fluke of a deck.
The best deck has 54% WR. One can argue if that’s still too good, but my understanding is it’s far from like 60% that Barrens pallies enjoyed
All in all the meta is diverse and pretty healthy, and better than Barrens at similar point in time.
But of course the mages will ignore facts and telling that this one blemish of them not being there means the game is crap and have always been crap or something.
