Being prepared is one thing, but having to watch a video is so fricking stupid I hate that. If a party finder demand I watch the video, fine it's his party. But man nothing feels more epic than going in blind; that said, I'm not going to be a hindrance to a random group of players i just met, so I'll run new content or content I haven't done with friends. But damn it people need to stop saying that watching a video is mandatory. Videos are so stupid, since the team make ups are different, strategies are different, etc. the only thing videos are OKAY for is explaining the fight mechanics, but not necessarily how to deal with them. If you want to watch a video, fine. But if you want to experience an epic fight and solve the puzzle on your own, don't feel like you NEED to watch the video. Just run with friends or make a blind PF.
