Yeah, I don't get it either. I cleared it the first time I attempted it very early on and we did not have any issues but I guess that stems from finishing very quickly meant those were mostly the "good" players who cared enough to level quickly. You are right though...the mechanics of Ravana are not difficult at all and are only a remash of old mechanics we have seen the entire game. You were probably playing with those who get never beat Titan HM. It is sad but what can you do but your best.
