Mines similar as both posted above. With a few exceptions. I start off with thunder then follow rotation above. But I don't use sharpcast with fire right away. If thunder procs off first cast, which tends to be when im about to cast blizzard, I use sharpcast, then hit thunder proc, then thunder will proc again which I use to lengthen thunder. Then it might proc again to lengthen again. To increase dot without downtime during enochian to recast it. Ill also keep up rotation, using blizzard when enochian is down to about 5-6. Usually by the time im enochian wears off, I can cast thunder again, and enochian is back up to go again. Is it the best rotation? Probably not. .. but im always casting f4/b4... with thunder dot here n there.
