Actually, looks more like ‘buffing singleton Warrior’ to me. That deck was somewhat vulnerable only to plagues and WoD Warlock practically, they’ve killed the first aspect and nerfed the second deck.
Nope, probably because there’s no reason to bother with such a weak aggro deck, compared to that turn-5-OTK Priest that was running rampant (they’ve slowed it down a little bit, so some things might change), unless you’re on a budget, couldn’t stand disgusting decks or had other personal preferences.
