That sounds pretty good given your gear. Get a hat of wintry doom crafted if you can't get a hat with a meta socket to drop, with a chaotic skyflare diamond in the meta socket--that should up your DPS a considerable amount due to the extra crit bonus, and enchant your weapon and helmet
Oh, saw the post about your rotation. Ditch corruption until you get 2pc t7, cast coa before immolate for a chance of proccing molten core before immolate. And conflag is a dps loss, you should just be doing coa>immo>incin spam.
