We managed it with a melee group in mostly columi, some Rakata, its doable with some effort

As stated, its all about sorting out the interrupts and ensuring the tank and healer are aware of which way they are going to kite. We did the instance with a guild group of: 1x Jugg Tank 1x Jugg DPS 1x Anni Marauder 1x Sorc Healer Once we established who was interrupting (Tank and Marauder) who was on adds (DPS Jugg) and we sorted out a kite path around the orbs it was cake. Just be on top of interrupts and good luck!
