because there isn't really a story to forked tower. its optional content for the sake of being optional. the storyline ends with the last quest, forked tower is just kinda there as mostly just a 'hey look at this FFV reference' and little more than that.
personally I enjoy the difficulty of it. The instance prog gets a lil frustrating but I think if it was just something I could show up and do more or less first time like OP is p much suggesting, I'd get bored of it real fast. Idk why people can't let some content be hard to access in a game where everything else is p much handed to you
making it easier to get into i support. As unique as this system is, when you require this much coordination to get any prog in I do really wish you could just queue in like DRS. But I don't want it to just be a glorified CE, that's for sure. OC deserves a challenging finisher in its debut, and forked tower does quite nicely. The hardest part is getting into it, but the difficulty of the fights themselves are just right.
