MI triggers the GCD because you arn't listed as having AP up. (takes about 1/2 of a second for the server to register that you have AP up, and to reduce the GCD on MI if you have it glyphed.)

Mana gem is right before the burn, without clipping the mana return on it.

Don't macro volcanics in there, I ususally pre-pot with a volcanic a few seconds before the pull, and then use the only volcanic for the fight during lust.
