I had such a hard time with this my first time. No one explained anything to me. I was still in the cutscene while they were saying what to do. After I got out I didn't have time to scroll up and read everything because tank had already moved towards the boss. I got knocked off. After 3-4 tries, finally finished. Everyone just has to watch their surroundings. Titan is fairly easy to heal. Gets easier when you get Regen at level 35. Only time I've had problems is because the dps refuses to move when Titan is charging up for his fist attack that automatically pushes you off if hit by it.

I also want to ask if he's attack kind of bugged for anyone else? I remember first couple times I got hit by it I moved and he still targeted me and I fell off. SO now when I see it, I try to move as far away as possible.
