Only issue I would have with it is that I need to now pay attention to whether FS is still active on the target and needs to be re-applied. When running a team of 5, I don't have time to sit there and watch that, so I keep FS as part of the regular rotation so I don't have to think about it.

However, it totally depends on how you play which dictates the best method for each person. If you're running a team of 5 x shaman, then that would probably work just fine as they will all be using the same rotation. In my group structure, there's too much to micro-manage as it is that I don't want to add even more. That's just a self-imposed complication, on my part.

Though, your use of the "nocombat" flag has given me some ideas to improve my warlock rotation. Thanks! :P
