I'm at a total loss at what Armor each of the specs will use. My guess is that Frost and Fire PvE will use Molten Armor, because of the 3% crit. Arcane will use Mage Armor for the mana regen. It is also possible that we have to switch between Mage and Molten armor when we need more mana, for the other specs too.
For PvP I'm completely clueless, we have Mage Armor with resistance and knockback, Molten Armor which can damage ranged attackers, and Frozen Armor which gives armor and freeze/slow melee. The talents that modify armors are accessible for all specs. For me Molten Armor and the talent looks bad for PvP.
What do you think what armor should we use for PvE, PvP?
