I don't have HSreplay stats but I highly doubt that even shaman or odd rogue are at 70% win rate in legend. Aggro always has inflated win rates because it wrecks everyone at rank 14.
I've been calling for a BP / Barnes nerf for months, not because the deck is crazy good, but because it really, really sucks to lose to it.
Even shaman is arguably the strongest deck right now and may well get a nerf eventually because of that, but there will always be a deck which is "arguably the strongest deck right now" and if it isn't even shaman it will just be something else instead. However, there doesn't always need to be a deck which screws you over on turn 4 with a Barnes high roll. Nerf shaman or don't nerf shaman, I don't really mind, but please please do something about Big Priest.

Bizarre post. When any deck gets a "nuts draw" it usually wins - that is a nuts draw, so it will usually win. But it doesn't always draw like that.
And, even with that draw, it has done nothing until turn 6. Most aggro decks could have killed it by then.
Equally, the early hadronox can be stolen by priest or polymorphed by mage, both of which can then will a value game.
