This is an addon that deals with rotations for shadow priests. This more helps the novice to become a better dps machine and to better manage their spells. Can you get more dps if you are a number cruncher? Probably if you manage manually and have proper timing but the general wow populace need to learn these things. This addon does exactly that.
