In ER you actually get better at playing itself, in FF14 you learn a script, beat it, and the next boss you are back to being a complete noob. That’s why raiding feels so unrewarding, coupled with the fact that the biggest driving factor behind getting leet gear is usually to dominate (others) in the open world, which doesn’t exist in FF14.

Tbh the only content in this game that feels rewarding is doing deep dungeons solo, you can’t outright cheese or cheat it with plugins like you can Savages and Ultimates, at least not to the same degree, you are the tank, dps and healer combined, so everything will be on you if you mess up and compared to raids it allows for at least some sort of creativity and brain usage.
