To Square Enix, these are the reasons why I am currently unsubbed from the FF14.

Most of these points are very personal, and vary from player to player. But I agree with the next 2 points:

This is true. The Diadem was dead pretty after a couple weeks, because the formula was dull and mindnumbing. (I personally quit around 3.1 because of the Diadem, a boring 24-man raid (Void Ark) and a poorly tunned raid tier (Gordias)) But in general, content tends to be rushed and then it dies. It happened with a lot of stuff that wasn't attached to a roulette, since those were the only reason why some of the old content was alive. Stuff like certain PvP modes, the Diadem and old raids (Alexander and Deltascape) were turned into ghost towns because of what I mentioned. Thankfully they'll add a raid roulette in the next patch, addressing some of it. PvP on the other hand, it needs better rewards and longlasting incentives.

Was there a point besides achievements, minions, and mount to begin with? People can still go in in sets of 2-4, I rent out my FC airships to people.

This is also true and I mentioned it in another thread. You unsub and you're forgotten. They state that they are concerned about people leaving the game, yet they don't retreive any feedback from it. Polls and Surveys would be a nice addition, not only having the Community Reps jumping from thread to thread, reading everything in order to get some feedback... and hoping it doesn't get lost in the Dev's team spam folder.

They actually do act on the feed back. Takes a while to be implemented people just want results right away and lack common sense to realize that feed back is implemented in phases not days. Those with options or some type of solutions get more attentions. Being I work in a similar field all feed back is categorized by a team and passed up for upcoming patches. Related feed back from players does make a difference we just don't see it right away.
