I looked at all the pyromancer changes during the patch maintenance and convinced myself that that was where I was heading. I dusted off my 61pyro/sc/harb build and diddled with some macros. Then I isolated casts that would benefit from the 'your next three spells' and 'your next-non-this or that'. Moved Fire Storm to a place of prominence. And immediately realized I had bitten off more than I could chew. The rotation was clumsy and kalerts didn't pop so I had to resort to actually watching icons, The end result was maybe 10-15K DPS on a base of 180-190K. So, I went back to my old 58ELE/SC/DOM build, and with almost no tweaking, I was doing 250K.
Obviously, by the way I describe this, you know I'm no theorycrafter ... and I'm almost certain that the break thru for us mages regaining our old rep as the premier damage dealer lies in pyromancer. So, I wait for you guys to provide us all with some builds and macros soon.
