I've actually seen this idea getting more and more traction lately. The character, content, endgame, and gear progression has become formulaic and hasn't changed much through 3 expansions. Whether that's a good thing or a bad thing is a matter of perspective at the end of the day.

Personally (I'm likely to get flamed for this) I think the content release schedule is too aggressive. SE is expected to push out patch after patch in order to justify the monthly sub, and to that end they do a great job. However. I believe that, in 2 major ways, it hurts as much as it helps:

1) Players wishing to stay current with content cycles have to play until they are burnt out in order to keep from falling behind the relevancy curve.

2) The frequency with which new content is introduced into the game does not leave much room in development cycles for innovation. Basically, they stick with what they've always done because it works and they have deadlines to meet.

But hey, that's just a theory, a FFXIV theory. Thanks for reading
