Yea, the thing is that I've ended up soloing them, if even one random joined in and hit once, they would get 2nd MVP spot for the chest. I only initiate Dark and Light Disaster. Heck, I haven't even gotten my jewels for some standard raid bosses of the other elements.

I'll run the others if summoned by others and I'm in a hurry to get rid of my raid points (close to leveling or have to go leave).
