CM is a poorly thought out dungeon, as is Prae. I recommend, if you haven't already done Prae, to get any friends who are lvl 60 to unsync it and let you watch all the cutscenes (it's doable with 1-3 lvl60 players, so you won't need many to help out). Sorry you had to go through this, thankfully they don't do this again after CM/Prae.
