SenseiSoriel, I really hope you read some of the truly helpful posts in here. Not just the ones saying UR DOIN IT WRONG LOL. You should be able to throw those sleeps out (I do know how helpful they can be sometimes, and I too have done that on a ranged mob that the tank is completely ignoring and so on), and still pour your mana completely into fire most of the time. The reason you want to stick with fire until you empty and then stick with blizzard until you fill is because astral fire and umbral ice will buff their respective damages, and when you level enough to get 2 or more stacks of those respective buffs, it will buff your damage even more. It will hinder you more and more later on if you keep switching between them because you spend time in the null buff zone where ALL of your spells are doing less damage than they could be. However, if you are just leveling to get swiftcast that is ok too. I hope to see you healing sometime
