I'll just start out by saying I came up with this build for a friend, not a lock myself but was trying to find a viable destro spec with raid support and good dps.

Thinking rotation would be CoE > Life Tap > Immolate > Choas Bolt > Incinerate... to Conflag then rinse and repeat (working in Shadowfury with any extra time)
I have an aff Lock in my raids that would be using Agony so this lock would be using CoE. Also how would imp do for staying alive? See any Glyph probs or recommendations? Btw she is in 4 of 5 T7.5 and at hit cap without speccing into it.
