the way we did it was to go through these dps targets in order
tenebron
whelps (if more than 1 set spawned it was a wipe)
vesperon (lust)
wait for a wall and then go down and kill vesperon and shadron adds
shadron
unholy dk tanks sarth. once all drakes are down the dk should be able to use a cooldown to survive every breath sarth does except one. a priest uses guardian spirit or paladin uses sacrifice to let him survive the other breath
