Do you know that dungeon that a lot of people hate? Yes, I'm talking about Pharos Sirius. Well, I had like a ton of fun when we ran it fresh when nobody knew how to do it, and I still have fun running it with people experiencing it for the first time (I even prefer them to the "pr0s" that quit when they see that they got that dungeon in the roulette).
If someone doesn't want to watch a video before doing anything and experience content as some of us did when it was firstly introduced, they're in their right to do so, specially new players that haven't made a lot of friends or that don't have a FC yet. When I want to do a perfect run with people that I know that will know the fight I just go with my FC, instead of trying my luck with pick ups/DF and then complain.
