Okay, so given all these suggestions, here is the rotation I came up with: Leylines>Surecast>Light 3>Swiftcast>Fire 4>RagingS>Fire 1 (repeat till low on MP)>Blizz 3
(Oh, and of course, anytime a Lightning or Fire proc pops up, I use it)
Any thoughts, or tweaks I should do? I also throw in a Swiftcast + Flare + Convert on dungeon bosses sometimes
