Did it fairly easily with a PT tank, Marauder DPS, Merc DPS and Sorc healer. Took 4 attempts to get the mechanics, killed on 5th. Interrupt the boss fire damage, don't stand in aoe fire, expanding electricity bubbles. I (merc dps) tanked and killed the adds myself in the middle platform. 2 melee dps would be rough and require more movement though.
