This is probably the least impressive video, but its one of my first
I'm running 4 destruction warlocks through Hellfire Ramparts at Level 62 (it'd be super easy if i had 5)

Attempt #1 fail

Attempt #2 success

Commentary
I've respec'd to destruction, the plan is too kill things fast. If you look at the crits, it could work
Attempt #1
The plan here was for the imps to distract the 2 adds while i nuke the boss.
I dont' know what happened, somehow my shadowbolts landed last and i still got the aggro from the adds
Attempt #2
The plan here was for the VW to gain a little threat, 1 VW was meant to die as part of the plan.
It died.. and somehow i got aggro after my 2nd shadowbolt, 2900k crit booya!

nb. my macros fail when my main dies.. i'll fix that one day

If anyone has any advice or any alternative strategies, let me know!
