As a level 50 White Mage who only today quit a Titan battle after 50 minutes because of the DD's going to the four corners, or taking too much aggro, or not doing anything to rescue the rock-jailed character, I cannot praise your recommendation enough.

If people keep dying, then the healer gets all the blame, but nine times out of ten, people die because they do stupid things and the healer simply cannot keep up with all 3 others attacking and aggroing different enemies in all directions.

*sigh*
