Current State of End-Game Contents - A Blog Post from A Japanese Player

[Pibz]

So you're telling me all those people making farm group each and everyone of them downed the content without watching or reading a guide?

Right I believe you.

There always were and there always will be guides in every game that has any decent amount of players making up it's community, so i have no idea what point you're trying to make, because guides aren't a "problem" exclusive to this game. (not even by a very very very VERY long shot)
And people will mostly seek the path of least resistance, this is a given.
Even if for some bizarre reason there wasn't guides, there would be experience and people who would want to repeat, quite some times, a certain encounter to obtain something,those people would then filter out players who don't know what to do.
