I do remember seeing people criticizing the Endwalker patch quest story for being a "carbon copy of FFIV's story" which was an easy way to identify people who have never played FFIV because the Endwalker patch quest story has almost nothing to do with the story of FFIV outside of names, designs, and references. Endwalker Golbez's character has very little to do the character of FFIV Golbez (same with Zeromus), the story's premise revolves around FFXIV concepts not present in FFIV, none of the major twists/reveals present in FFIV were reused etc. You can say it leaned too much on FFIV references and fanservice which sure fair but the people saying it was unnecessary because we already have FFIV and that it was just the same thing again are clearly talking out of their asses
Though I do agree with the OP that Endwalker Golbez is still cooler than Speen
