It's important to note that Inner Fire no longer gives a spell power buff as of 3.3.5, so the points in Improved Inner Fire would be a waste. I prefer to max Twin Disciplines, max Improved Power Word: Fortitude (for buffing purposes), then put four points into Unbreakable Will (partly just to get down to Meditation and Inner Focus and also because time spent silenced/feared/stunned is time that could be spent DPSing), and then max Meditation and Inner Focus. It's mostly the same as what Aliena has so kindly posted for us above, but here is the build I run with: http://www.wowhead.com/talent#by0buZ...ffqfzAo:hqazVc .
EDIT: Also, all of the above rotations (mind flaying to get to 5 stacks of Shadow Weaving) assume that you are doing a longer boss fight. For shorter fights, it's best to just get all your DoTs up, mind blast, and then mind flay until either mind blast comes of CD, DoTs need to be refreshed, or everything is dead.
BEGONE FROM THE INTERNETZ TROLLS!!!! BEGONE!!!!
