I don’t really feel like anything is going to change too dramatically. We’re still going to see the basic setup involve a lock, mage and dk, with a rogue thrown in if you want to win. Warriors are still pretty brilliant, and with the buff to resi I feel like their pressure can actually force something from healers (we ran a triple warrior / four healer comp very late last night, pure aids for the other teams).
I don’t think I’ve faced a single team without a guardian druid yet.
Seeing no hybrid specs at all, nor do I expect to.
