I decided to solo this guy because i havent seen a warlock do it yet.
started recording a bit late so missing the first 10% or so but nothing exciting there anyway
The Paladin in the Raid was in Dalaran so did not help(was just there to give me a raid group)
Random Info:
spec used: SL/FG 27/44/0
saved Demonic Empowerment to get pet out of Enveloping Winds if things look bad, portal down to return from the knockbacks and a bit of nature resistance for the pet stops alot of the Enveloping Winds(T2 5 set bonus is nice here) kept curse of weekness up all the time to lower his damage on pet and on myself if i take a hit, soul linking the pet helps break the Enveloping Winds which means you can save Demonic Empowerment for when your moving corruption should be up all the time and drain life / health funnel as needed also if your in a good position it is worth doing some fire damage when he is week to it, if you relise you are gunna take a few hits death coil is a nice heal, but if he hits you more then once (maybe twice) in Supreme Mode then its over.
Buffs were all self applied, Kings and MOTW from the LW drums and Stamina from a scroll
Once i had the tactic sorted it was quite easy but the run backs from wipes are painfull
