SimC is kinda broken for mages. It looks like you are gemmed correctly, although with the lower level PBOI, I'm not sure if it's worth it go gem all expertise/haste, versus int/haste. Even with PBOI, i'd probably favor reckless > wicked vermillion onyx under 550 ilevel, but that's just opinion since I don't have data to back it up.
Feel free to ask questions regarding rotations. I will say, once you have logs, take a look at your uptimes on your level 75 bomb, and your invocation. Invo should be above 90% (95%+ is better) on every fight, and bombs should at least be 80% (90%+ is better).
