What a weird turnaround. Now if people want the CHOICE to do this and skip the cutscene they can make a PF and make sure everyone agrees to DC for every cutscene, or at least agrees that it's OK.
Though only time will tell if SE considers this reportable. Though I know I'd report people doing it in the MSQ roulette, it sounds like it's directly circumventing the intention of the change. I think as has been said it'd be pretty easy to make the case that someone is doing it intentionally if they DC immediately at each CS, rejoin and rush through the rest. Even then if one person is doing it, sounds plausible for connection problems. Enough people to finish the story synched KEEP having that happen? Little fishy.
