If blizzard calls this balance among PvP lovers, then, they're drunk. Patch 5.1 brings Warrior nerfs and Mage nerfs, Hunters are getting buffed because they can cast spells while moving, good move blizzard.
There are already to many people complaining and blizzard keeps crashing things. This game gone to shit and not worth playing anymore.
The main reason is probably that shit firmware called Activision.
