You know I'm wondering the same thing after burning through soooo many teams for titan HM... Don't get me wrong I can do the fight just fine on the two easiest jobs in there you know Paladin and Bard, but the second I got in a casting bar no matter when I moved I'd get hit by plumes. I was told by this overly geared healer who is good at what s/he does that there was no reason to help a person who can't dodge in titan through titan...

I'm starting to get more confident after managing to heal garuda EM, but I still feel like a crappy healer and would like to get over it ;n;
