Yes OP, this game has longevity issues. They really ought to start addressing them.

With FFXI I never, ever had that issue lol.
Yep ;;

It felt it had more longevity because everything took longer to do.
Not really just that, there was also a lot more to do. In fairness, it took a few years for the game to reach that state... but that was also a different sort of game altogether, where up until the level cap was raised, stuff didn't just get replaced every 3-6 months.
