I am with you on this but you can still get a really good weapon without Titan HM...Moggle Weapon iLv80. I really think you need a better group though. They need to fix this fight but they probably never will so all I can offer is that everyone in the group needs to learn how to pre-dodge and just learn Titans order of moves for each phase. They key is playing with the SAME players everytime so you know you are all getting better together and you learn to play together. I got it down on a PUG group on one of my runs but I got lucky and we were all good.
