There is only an opening rotation, after that it is all about popping procs and a priority list of abilities as they come off cool downs. I am assuming you're applying this to boss fights. First you should open with CD and get the tick going. Then affliction, followed by thundering blast. Get that cool down going right away. Pop shock, then LS x3 or until you get chain/ce proc. Hit those right away. Go back to a quick shock or LS if your TB is not up yet. After that its all about priority...Keep affliction up, TB, chain and FL off proc from LS. Shock on cool downs.
