I have been hesitant to do this dungeon because of this. I did CM for the first time yesterday and, luckily, the group didn't get mad for me watching the cutscenes, but they were moving on while I was watching them. I felt a little bit like a burden. I might wait for more people in my Free Company to hit 50 before doing Praetorium so we can do a story run. I really want to do it so I can get my GC weapon though.
