See my quest is a. Why use blizzard 3 at all? And 2, why use thunder 2 over thunder? My standard rotation (Without raging strikes and potions just to be simple) is Thunder 1 - Fire 3 - Fire spam/Firestarter proc - Swiftcast - Flare - Convert(Or saved for raging strikes/Potion nuke, depends) - Transpose - Refresh Thunder - Fire 3 - Etc. By the time I cast thunder 1 and fire 3 my mana bar is totally full. So why blizzard 3 and thunder 2? It feels like a waste to me because I almost never run out of time on my thunder, and my mana bar already refreshes quickly.
