I definitely feel like this game never really has enough content, especially if progression raiding doesn't interest you. That's why I unsub for roughly half of every expansion. Never really had that issue with WoW. If I unsubbed from WoW, it's because I was bored of WoW, not because I ran out of things I could do. It would be nice if there were more things to do, but I'm not going to hold my breath. They seem pretty content with their formula. All of the random nonsense that got added in ARR seems to have been a fluke.
