I'll tell you what I did. I DFed until I knew titanHM, then when I could avoid the avoidable damage comfortably, I went in PF. Did exact same when my friend needed titan for his relic. Brought him in DF, then went PF. U need a comfy group for titan tbh. DPS have to avoid the avoidable damage so healers can heal the tanks + heal the unavoidable damage whole group takes ( tumult/geocrush ). It isn't hard at all, but the difficulty of finding a kill group in most cases eclipses the difficulty of the trial itself lol.....
