Every game with any kind of build, gear, skill and character choice will have a "meta" for specific goals. Thankfully that doesn't stop them from continuing to be made.
XIV community just happens to be extremely unhealthy obsessed with META even if 99% of them would never be in condition to race for world first and for literally any other purpose as far as raiding goes it doesn't matter.

This won't change. It's ingrained in this community's culture and enabled by the developers.
