This is actually really sad. It basically means all the really neat, fun and powerful 8-mana and up cards they print are essentially unplayable except for priests and warlocks trying to beat the curve.
The game needs a certain level of aggression to be healthy. But they’ve vomited out so many overpowered 1-3 cost cards nearly every expansion that they have effectively painted themselves into a corner.
I hope AV has some low-cost anti-aggro tools coming for most classes or the problem is just going to snowball.
