I have to complete this quest, haven't tried the fight actually I just want to get some gear first because I'm healer, but I saw the same with Titan HM, people that just quit after one single wipe, I don't mind if I have to wipe 20 times but sadly that's how it is. At the end I finished with a really nice group with the DF, but took me some time. When I'm ready t face Garuda EX I believe that I'm going o search for FC so they help me out.
