Yesterday I got the chance to do Koralon, the new boss in VOA. I did the 10 man version with a pug. We two shotted it. I was one of the two Druid Healers.
The fight was not very difficult to be honest. As long as the two tanks stack and you have some good AOE healing you will be fine....and stay out of the fire. There is lots of fire. We two shotted the new boss in out first look at him.
The whole strategy is:
a) Stack Tanks. If you dont, metor fist will smash their faces in.
b) Dont stand in fire. Just like most other fights...stay out of bad stuff.
c) Heal your ass off (if you are a healer). You will have to do ALOT of healing if you are two man healing it. I did 3400 HPS for the fight and the other Druid did 3100 HPS for the fight.
Also, for those of you who didnt notice, there are now faction changes available for 30 bucks. All of the questions are answered on the official forums. Check it out.
