In my last article, we looked at the Warlock in alpha: Atrocity, Metamorphosis (yay, demon form!), Decimate, and new synergies between our spells. All three top tier talents seem to have more utility in PvP and the Arenas, with Atrocity possibly having some amazing utility in some PvE situations. The synergy between DoTs and nukes is something to watch, particularly Eradication and Everlasting Affliction. New additions to the Destruction tree that seem to encourage cross-school casting turn out to be just minor improvements to the tree's PvP viability in their current form.
We turn our attention now to the other talents, and Blizzard definitely plans to make Spirit matter to warlocks.
