Catch all the fish, craft all the things, win all the raids (both present and past), make all the relics, do all the quests, furnish all the household, PvP all the n00bs, collect all the glamours, and whatever else you can think of that might be out-of-the-box.

The game has plenty of content. I've been playing since ARR release, and I've never had the time to do all the things I want to do in game; I never run out of content, not mid-patch or any other time.

Perhaps not all of these things are things you're interested in doing - but SOMEONE out there is. The game provides enough content; it's up to you if you want to partake of it.
