Older content should become naturally easier with better gear and also through experience with the content itself not with nerfs, though that pretty much applies to all content really and that better gear will be easier to get with uncapped myth or drops from the dungeons themselves. Nerfing content that was already nerfed twice is just a sad practice, I still remember how it was actually somewhat challenging and fun doing AK on the very first two weeks of 2.0 doing it in with half AF half militia gear and even some GC gear, really whatever highest gear from 1.0 we could scrap while still farming for DL, myth AF or even a relic. The issue with AK was it being the only dungeon, out of arguably only 4 endgame dungeons not counting Coil and counting both final story dungeons, that dropped myth and substantial philosophy so everyone got understandably and rightfully tired of it, the mobs also didn't drop any gil so it was more effective gear damage wise to skip everything and have the tank die thanks to the wonky durability system.

Then there's the issue of EX primals being only 3 months old and already having an echo buff applied to them, I get some people just want to clear stuff for the story and have multiple jobs and families and it gets tiresome when someone screws up, including myself, and that content can't be cleared, but really it just feels better when there's an actual challenge behind it and it feels like you earned a victory and it wasn't just handed to you even with multiple wipes. It really isn't an elitist attitude or whatever you want to call it either, I really still don't believe there are people who are just that inexperienced with MMOs or videogames in general for content to be that much difficult or even outright impossible for them or that players are that "casual", even after seeing how bad things can get having cleared HM Titan before 2.1 using the DF only twice out of almost 100 runs and me dying on the second DF clear, and yes you can turn the buff off but honestly I don't see many people doing that once it's on except for "fun" runs with say a FC group. Though honestly that's how the game was shaping up from the very beginning with story quests having NPCs added that weren't needed or poison damage being nerfed into the ground in a certain quest that was also kinda fun before the nerf, and sadly that's how the game will keep going towards the future, if you don't like it leave, stuff, can have, etc.
