I agree Youtube to a point is great to watch, if you are looking for a clear and have not done it. But i really recommend actually playing thru something for the first time without any guides or videos. Only content i think Youtube or guides are best viewed for is endgame (coil) content. Otherwise every person agrees to having a totally random group when they sign up for Duty Finder.

This also applies to the "at least have watched/read a guide" party finders. What is it with people that just totally disregard a simple request hoping that the rest of the group is good enough to carry them while having to explain everything. The reason people post that message in party finder is because they know what to expect and can better adapt to it with a random group of players. If you want to experience everything for the first time without the drama, ask your FC. that is what they are there for.
