Hearthpwn

The bundle was better overall (5 less packs for much more dust), the whatever meta there is now is mostly fun (Actual nerfs pending), and though stupid highroll decks (druid is just one), it's a strong meta, not DH-sided, not HL hunter-sided, and not we-gonna-kill-6-decks-the-last-moment meta (though they would).

The fact we got duals just gave more classes options not AS available before. With that said, Warlock/Priest are askewed towards Warlock as hell, same with Warrior/Paladin in my opinion (excuding barov). Rogue/mage I think is The success here, and the warlock/dh bundle works very nicely, while if shaman wasn't the concurrent bitch (p.s. shaman is good, but terribly balanced in other classes' favor), I'd put mage/shaman right after rogue/mage if not best duals. 

Duals made the game better, if we paid $10 mode, this time at least it feels like it's worth it.
