Endwalker is definitely a low point in the game for me.

The story is good but hardly great. For every high point there is some considerable drag. It was always going to be hard topping Shadowbringers but I feel Endwalker is much closer to Stormblood... which is not exactly a complicate even if I do feel Stormblood's MSQ gets too much criticism. What really damns Endwalker is the severe lack of content longevity. Almost nothing lasts this expansion either due to paltry rewards or simply there being no actual reason to continue doing whatever releases beyond a few days/weeks. The two major selling points of this expansion were Island Sanctuary and Criterion which... haven't exactly gone over well for the precise reasons I just said. What's frustrating is they both have so much potential but we keep cycling back to the utter lack of longevity. Island Sanctuary becomes nothing more than a glorified retainer venture you visit ten minutes a day or once a week. There's literally nothing else you can do with it once you get the ball rolling.

Say what you will about Eureka or Bozja. They may have been flawed but they gave you a reason to keep playing. The same cannot be said for almost anything Endwalker has offered.
