Far from it.

They put in a decent update with battle content, story, quests and quality of life improvements every month. This game is showing no signs of dying down. It will be going strong for years to come - it has a loyal subscription base that clings to it for dear life. The only time it was thought the end could be near was upon FFXIV's release, online users at any time went down to 80-150 per server, even then they were still releasing content (had the numbers stayed that way however, it will have ended pretty quickly). Now that the excitement for FFXIV has died down, you will see a much healthier 400-2500 online users per server at any time, these figures have been stable for half a year now.

I don't ever intend to quit. I tried to quit once, and found myself spending much more than £11 a month buying other games to pass the time spent while at home.
