Ok so the game is moving away from infinite value. That leaves 3 grindy control decks: Shaman, Warrior, and Rogue. Rogue has the worst healing, but makes up for it with insane value and tempo. Shaman has lots of value generators and is ok at tempo, but lacks consistent defence and explosive plays. Warrior has the healing and value, but lacks the tempo.
Wow guys I think blizzard is actually learning to balance the game.
I also like the direction they are going with these cards, but I don't think we should jump to conclusions. We've only seen 4 legendaries om the set.
