I can just imagine them just making Thunder have a higher proc rate under Enochian so we'll be further tempted by the Thunderstorm procs we can't use. Anyways.. I don't really see the point of using swiftcast in the opener IF you can precast the Fire 3 to hit as the tank pulls. Hard casting that Fire 3 should result in more DPS in the opener. If it's a situation where precasting is not possible then the Swift Cast will indeed be a DPS gain.
