Okay, you've gemmed for spell hit rating, and this is great. However you could also enchant your gloves for it. Whatever spec you run that's a little more DPS. Small niggle, but you've wasted points in supression, you have 14% hit, so only need 2%, anything above that is wasted, drop 4 points out of supression. Get grim reach and destructive reach too?

The pet controller on Maulgar always does great damage. You have a level 73 elite pet. Say no more.

Other than that, it's down to the timer. You had about 16% DoT downtime on UA and corruption.

To be honest though, generally, you should grab a little more hit, get crit (maybe half a percent) *without socketing for it* and then go back to destro if damage is all that matters (and you're not malediction or 5/5 shadow embrace). I'd reccomend replacing alar's crappy band with the nethergon band from the heroic badge vendors.

Oh and badge loot has better stats than T5, and the set bonus is pretty useless for non demo locks too.
