Like many suggested setups we used a Frost Spec Death Knight to kite the parasites for the entire encounter. We also used the ‘grouping up on melee’ strategy. Standing ‘outside’ were Myself [healing the DK], The DK, 3 x Hunters MD’ing the Constructs to the Off Tank and a Holy Priest.
Having 5-6 ppl Standing ‘outside’ away from the main group ensured the ‘Pillar of flame’ and ‘Constructs’ would always spawn on one of us rather than in the melee and basically cause a big mess.
As usual I was Disco spec – which allowed me to bubble myself, the DK kiter and the Hunters whilst using Inner Will for the added movement increase….you need to be able to react very fast when fleeing from a pillar of flame or construct !!
As we entered Phase 2 we all spread out [6 yrds apart] and basically nuked ! popped any healing cooldowns that we could such as Divine Hymns/Tranquility/Divine Guardian etc and said a few prayers 🙂
Anyway here is the video – Frapsed by our Fire Mage ‘Peedyweedy’.
