Yeah I should've been saving since people announced things about those scrolls. Gonna start saving now, should have a good bit of gold by the time the expansion comes out.
Also "buffing" a class after a card expansion is obvious. All of the classes got buffed because they have new good cards.
That being said, out of the 3 classes that were shown, hunter seemed to be the strongest, with mage close behind. I think hunter will be more fun to play now though, as it's switched from just placing OP cards over and over, or rushing your opponent's face down, back to the 1 turn combo turns like you saw in Miracle Rogue, the old Starving Buzzad/UTH combo hunter, savage druid, etc.
