Yeah I'm in the same boat as you. I'm trying to do Titan HM right now and I've deemed DF useless. But even trying to start a group up, it's starting to be the same people over and over and we get nowhere since there's always at least one person who just keeps dying. It's frustrating because I have no control over it and I know I'm personally capable of doing my part in the fight.

Give me a tell when (assuming you aren't there already :P) you get to Titan. Or hell, even to help you get through Garuda if you haven't yet >.> My FC has only a few level 50s so I can't get a full group running, but they'll help out how they can, since a couple of them already have their relics. I can always use more people to try and make it through with :P
