Malteor Flamecaller (Heroic Version, Underdepths)

Been having issues with this mob when the group doesn't have mass amounts of DPS and you can burn him down within 2 or so AOE's. Looking for some advice on how to kill this guy.

There is no real tactic to this mob, despite of dpsing and having a healer with you that understand its class. Been dooing this mob, every now and then, almost every healer class, can heal em solo.
It still depends on gear you wear and the healer if it´s doable
Most of my chars wear reaidgear... maybe a reason ^^

As I recall, one add is named differently, and if you have a weaker group you may need to CC it or kill that one add.
