One day all my WoW friends and I decided we were burned out on playing the exact same night and we all quit playing. Five months later I decided I wanted to log in and find something to do so I sent a mass text and we all started playing again that same day.

I've bounced in and out of playing FFXIV four times because I don't have any friends to play the game with.

To actually quit when you want to keep playing would be rough. My last military deployment was when I was pretty involved in WoW and I would have withdrawls/look forward to when I made it home to play again the whole time I was away.
