Which was extremely well done, and has everything people need It also doesn't tell people NOT to use the DF to do HM Titan. Not sure where you got the, "It is NOT recommended to use the Duty Finder." or even, "Don't bring two tanks, just an extra healer."

Seems a bit elitist, considering DF is fantastic for learning the fight, and in my experience...we beat him quite often in DF. (with two tanks, even!)
