The biggest problem aren't the progressive content or the community. Its the lack of interest that most players have who are not playing good and i'm not talking about new players here.

You have players who have several jobs on level 60 who don't use any sort of rotation or cooldowns, they meld materias in their gear that make absolutly no sense at all and if you try to explain them what they are doing wrong (and yes in a friendly way and not as flame) you get answers like: "I play the game how i want, i paid for it." or "You don't know anything about the class since you are playing (insert different class as the one that you tried to explain)!" or they don't even react at all. That stuff is a complete lack of interest and the fault of these players not the content or the community in general.
