I am Etherwind of US-Darkspear and have taken over development of the original facemelter and pushed it into the current age. 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.
Finalizing the Face Melter one project with a few more bug fix versions as I am developing Face Melter 2! The new code will be able to handle more changes and will add MANY new features including latency compensation, mind flay clipping support, and movement compensation on spells for maximum dps, and even more past this small list. I will also allow me to fix things without checking a obscene amount of code as well as streamlining it and reducing bloat. Once a public Alpha is available I will be posting it to the optional files section.
Face Melter 2 is now dubbed Face Melter Zwei and features a new visual design for the suggester frame as well as support for many new features. The first release test alpha is scheduled for 2 weeks from now. Among the added features are cooldown indicators (covering Shadowfiend, Dispersion, and Inner Focus), Record keeping for the last two prior spells casted indicated by the new GUI. Latency, cast time, and GCD compensation and cast planning. Turn off SW: D and Mind Blast completely or only have them used in certain conditions (ie. Mind Blast used unless under Heroism/Bloodlust or SW: D only used when target is under a certain percentage or while moving). Support for primary and secondary specs. And many more things planned, also I applied for a Cataclysm Beta Key to plan a Cataclysm release.
