I also don't see the point about lateral upgrades. Most gear in 75 era was absolute garbage, most gear for leveling was simply an increase in defense, and maybe 1-4 to an attribute, which mathematically is EXTREMELY minor. At endgame you had very limited good options as well. The best WS set was usually from Sky, the first endgame instance of the game, and in most cases that never got beat during the 75 era. The belt TP belt in the game was level 55, unless you were a MNK. The itemization of 75 cap was garbage and usually there was one totally amazing piece that shown over everything else, and the difference between most other pieces was almost entirely unnoticeable. Whereas today I have different tiers of TP set based on needs for TA, STP, DW, DT, Accuracy, magic evasion, etc. I have 13 different Ambuscade backs for my THF, and they see use. I have multiple sets of weapons, and I actually use them. 75 days I had a Mandau and that was done, no other mainhand dagger needed. Today BiS mainhand weapon will differ between Twashtar, Aeneas (sorta), Tauret, Malevolence, Vajra and Gandring depending on what you're aiming to do. When it comes to lateral upgrades, 2019 FFXI absolutely destroys 75 cap FFXI.
