I don't mean to be that person, but I'd expect this kind of obsession with WF in say an MMO like WoW since it is a very min max heavy MMO where people tend to care more about builds and ilevels and if you don't have the right talents or ilevel or what have you then you get a swift boot and a spot of mockery. FF14 doesn't strike me as an MMO where getting WF is as important and it's far friendlier in terms of just general class play where people don't have to really worry about being...competitive I guess? The devs focus more on fun rather than competition. Even if WF was reached, what then? You enjoy getting to brag about it for a bit and you get a fancy weapon to show off. That's it. That's literally it. You give away so much time and effort for what basically amounts to bragging rights for a couple of patches until the next ultimate or whatever. Seems like a lot of effort being put in just for validation. Validation which imo doesn't really mean much in FF14.
I would imagine that a large portion of FF14's "extremely hardcore" raiding community comes from (in some capacity) WoW's "extremely hardcore" raiding community. Doubly so as FFXIV seems to get better and bigger where WoW is really struggling.
FFXIV doesn't much of the horseshit that WoW does and an effect of that is simple - getting "raid ready/WF ready" in FFXIV is a much smaller time commitment than it is in WoW.
There isn't much "min/maxing" in WoW currently and the devs have taken a great deal of effort to root it out, what there
is however is fucking grinding. For corruption, azureite, titanforges/warforges/mythicforgers, whatever the fuck will fill up a bar that makes your character do more damage without much input or skill invovled. There's still a skill ceiling involved with the WF races but it is possible that another player in the same role will get "luckier" than you and have more titanforged+ gear or have the gear roll better stats and have him, assuming all else equal, perform better than you. This gets worse as you realize the enchants, flasks, and augement runes cost $$$ or grinding on top of that.
FFXIV doesn't have that issue - gear is really easy to come by and comes with tons of "bad luck" protection that effectively means every new raid tier starts all raiders on even ground - 8 weeks of clears means that
every raider will have
every single piece of gear they could possibly want from a raid tier, if it even takes them 8 weeks. FFXIV has very limited "gear tax" - no trinkets, no enchants, 1 food consumable, 1 (essentially) usable potion. Gear comes with a few materia slots and materia is super-widely available (and is removable from gear) and that's it. It's all really inexpensive and easy to come by.
WoW is hurt harder by "meta" shifts as well - as each WoW character is a seperate character. If you're a Warrior Tank and they get nerfed and now Prot Paladin is the new "best tank" then your WF group is going to expect you to roll one (or find someone else that has one) and not only do you have to level it - it will not get access to any of the gear the Warrior had (including any rare "titanforged/corrupted/whatever" gear). If you grind in WoW you'll have access to herilooms to make leveling easier, but if you didn't - then you don't.
FFXIV has all classes on a single character, meaning that if you want to switch from Dark Knight to Paladin - assuming you have them both leveled - it's instantaneous. All of your DK's gear can be used on your PLD (minus the weapon, which can easily be gotten). If you don't have them both leveled - PLD (and all classes) get a built in EXP boost, no herilooms needed (or grinding for herilooms) needed.
FFXIV is mainly fun-centric and not a huge amount of people care about World Firsts - but the devs do cater to the Hardcore/World First crew through the "Ultimate" tier of raids, as well as the "Savage" tier. They just don't cater to them everywhere.
