Havoc Demon Hunter DPS Rotation, Cooldowns, and Abilities
Section 5 discussion opening rotation for AOE, I think Glaive Tempest should probably be step 3 if the player has chosen that talent, since the author suggests casting it after Meta and before Eye Beam in the single target rotation. I could be wrong but sitting on an available Glaive Tempest throughout the opening AOE rotation seems like a bad move since its an instant (w/ global).
Or if I'm wrong, maybe some text on that section to acknowledge why its not cast, would be interesting to know.
