Ive been thinking of respeccing my long-time holy priest to raiding shadow. I took some time to look at the tree and plan out my spec as well as look at the specs of a number of shadow priests in high ranking guilds. What I came up with was this: http://www.wowhead.com/?talent=rVMhzhZZxGttMxRhtxo. However, I noticed that very few people whose specs I looked at had picked up improved mind blast. The only reason I could think of for this was that Mind Blast was not used frequently enough in a shadow priests damage rotation to make it worthwhile reducing the casting time. Is there a standard rotation of abilities that most raiding shadow priests use to dps? What would you spec to raid dps as a shadow priest?
