I find it extremely interesting that FFXIV is suffering from too much end-game content coming into this next expansion when so many MMORPGs suffer from a lack of such content. Personally I enjoy having a ton of story that can't just be skipped over, because that means it's integral to the story line and it means that players can't just skip over story dungeons and not know how to play their class/job in a party setting.

In fact, while it may potentially burn out new users, it will definitely make them veterans of the game by the time they hit Heavensward content.
