This is a theme park style mmo. It is designed in a way that you run out of content.

unless you like vanity items.

SE designed this game to where you have play another game at the same time. There is just a massive lack of content, and the design philosophy of XIV will keep that massive lack of content even with new patches due to vertical progression only and constant content negation.

Just like a theme park... even the best rollercoaster gets boring after you ride it for the 100th time.
