Again, it is very hard to classify casual vs hardcore, because many of the aspects are interdependent. I can be very skilled but i may not have an end game linkshell, does that mean i am blocked from experiencing this content? I want to advance the storyline too and experience the dungeon, but i only play 2 hrs a day and i dont have any friends online.

In my opinion there should be content for both. The end. Have the content or dungeon adjustable by difficulty so all dungeons and content can be experienced by everyone.
