This... this is bait right? Please tell me it is bait.
Jobs had identity - Ah yes the Identity of Dragoon dying if a boss coughed magically in their direction. Or Paladin going 1-2-3 again... and again... and again... There was some good job identity, don't get me wrong. Like Bard and Monk but uh... there was also a lot of very bad identity too.
Jobs had a reason to level multiple (cross class system) - The Cross Class System is one of those 'good on paper bad in practice' things. It seems like a neat thing. Until you get a healer who refuses to to get Swiftcast because they don't want to level Thaumaturge, or a Warrior without Provoke because they don't want to be a Gladiator and other similar stuff. Which happened faaaaaaaaar too often. Hell it was just not very intuitive either as a lot of sprouts didn't even know they had to do those things to get it. Or even do those things to unlock jobs. Remember when you had to level Conjurer to unlock Paladin? Pepridge Farm remembers and says good riddance.
Hunting log and the Hunt kept the overworld alive - As others have said, the hunt is still there, the hunt log was kind of pointless beyond leveling. It was the Fate trains that kept it alive. The best way to level at higher levels was to hit up the Central Coerthas or North Thanalan Fate Trains.
Things weren't handed to you (you had to work a lot harder to clear content and save allowances) - I uh... not really? The primals were a lot simpler, and hell the real challenge of Titan EX was the netcode and lag and not actual challenge.
The raids were harder and had more complex tank/healer mechanics - Eh... some were, some weren't. It's as hit or miss as it is now.
The dungeons were harder (lost city of amdapor anyone?) - Lost City of Amdapor was face roll easy at launch. The only one I ever saw that people struggled with was Pharos Sirius.
The relic was harder, involved the over world and HAD a gil sink, AND dungeons even contained some of the pieces, AND crafters could make money selling the weapon needed - Harder is subjective. Sure the relic specific trials were neat, but simple. Atma farming and books weren't hard they were just FF11 nightmare grinds.
levequests had meaning - Battle ones yes, I will give you that. Battle Levequests are gone for a reason. Gathering and Crafting Levequests still have plenty of meaning.
Grand company was useful - Eh? Not anymore than it is now. Sure a lot of materials were locked behind Grand Company seals but that was frankly it.
Glamour system was more robust - Okay you lost me here completely. HOW?!?!
Elemental attributes on gear - Was pointless. No one did this outside of super duper niche situations.
Tradeable raid glamour meant raids had value in clearing them weekly (the dreadwyrm attire) - As others pointed out, this was a HW feature not ARR.
