MMOs have a shelf life on content and if you were not around when it was hot like Ravana or Bismarck story mode, you're going to miss a point in the game where 100% of the players were new or have similar gear. Today some people still get wrecked and falloff in Ravana because the tank doesn't realize they need to stop attacking when the shield is in-front.

Let us not forget the salty people in Stormblood when they complained that Shinryu trial story mode was "too hard". YoshiP never touched it once, they just let the player base catch-up.
