Oh you mean like the several mounts including Gabriel (x2), Deinonychus, Al-iklil, or the Construct 14 mounts, Wind-up Gunnhildr, Helldiver F1, and the Dainsleif mount, and the Cerberus Mounts? No I remember perfectly clearly thank you very much. As for with regards to glamour, a vast majority of those were direct reskins and reuses of old gear. Pagos? Check the Arachne Sets, Anemos Expeditionary gear? Check Valerian Sets. Anemos Jacket? Check Gyuki Leather DoL Lv63 set. Just reused assets. I'm sorry but there's very few unique assets in there, including Scorpion Harness, Cassie Earrings, Penthesilea's Spear, Shantotto's Staff, and Absolute Lance, and the Elemental Gear. On the other hand Bozja had both the Law's Order gearsets, and the Blade's gearsets.
I would beg to differ in that the difficult came largely from how obscenely annoying they were to spawn, but in either case the difficulty of one over the other would largely be down to perspectives and opinions. But if this would be your opinion of the difficulty then to be frank I would argue that the state of the dungeons has been this way long before Shadowbringers was out, because to be quite frank they were no better in Stormblood. You liking or disliking the aesthetic of them quite frankly has very little bearing or relevance to the content itself. Otherwise I could make the claim that the open world Stormblood zones were just sloppy, at best.
I think you're remembering this backwards, Eureka was the only way you could upgrade relics, whereas the Bozjan ones you could complete in a variety of ways including doing FATEs outside of Bozja itself, doing raids, or by doing 24-man raids. Arguably farming mobs and dragons arguably really only applied to Light, otherwise the only way you could obtain Pagos, Pyros, and Hydatos Crystals to my knowledge was by farming NMs, or more appropriately a renamed FATE. You probably haven't done very many Eureka relics if you didn't think Eureka wasn't subjected to the self-same abysmal circumstances that you've attributed to Bozja. You know, seeing as practically every single NM was locked behind a 2 hour respawn timer in addition to their spawn conditions (Inc. Gales, and Heatwaves in the case of Anemos/Pyros - You know, both of which can be several hours apart.). Nah they didn't have time gated instances, just time gated NMs instead which to be frank is even more abysmal.
