I think current relic is fine, you can do the new content(for most steps) or you can do old ass grindy content like you're farming light/atmas on every steps, which imo is fine for what the relic is.
They do need better balance between the options however(they did hotfix some of the stuff in that regard) but the first couple of steps can be done in Bozja with farming parties faster than it can be farming FATEs+60dungeons outside but if you don't want to bother actually working for it having a braindead easy option is nice enough.
The crystal tower step can be done in CLL very quickly, just need to camp the spawns, took me an afternoon to do my 2nd relic this way, but I was mostly afk alt tabbed and only checked every now and then for new instances then afked until the spawn timer, so it was a lot more relaxing than running Syrcus 15times.
The one time only step was pretty rough but was hotfixed to be more decent and the last step I think is perfectly fine since it gets you to run new content(DR) or to run old content with an emphasis on running it in a way most people haven't(doing 100+ potd, which a lot of people didn't even know existed since it stops at 100 in random groups).
Overall I'd say it's the "best" relic they've done, in the sense that it doesn't fucking suck dicks to do. It's a lot faster than previous relics, and it gives you 2 different options for each step depending on whether you want to work actively on it or just grind it out while not paying any attention, and that's great imo. It is probably the most "boring", but I'll take boring over ARR atma(original rates)/books or Anima sands(before the buffs) and definitely over Pagos light farming(even after the nerfs and even after the current echo).
I'm going to disagree on the expert recipes. I think they're just as braindead as other stuff...just a priority system basically and back to using Hasty Touch and Tricks of the Trade like it's ARR or HW.
I'm not saying they're riveting challenging content, but they're the least braindead type of crafting content they've added, because you can't macro them so you have to actually play the crafting minigame, and it is a bit deeper than the original ARR minigame too since there's more different proc types. It is a priority system obviously so once you figure it out you just go through the steps, but when the comparison is pressing your first macro then waiting for the sound effect to press the other macro, it's not really hard to do less braindead. Still pretty dumb yeah but it's not like crafting was challenging content in the past as you mention too.
Even back in ARR when macros weren't as much of a thing, crafting was still super braindead. The main "difficulty" back then was being able to afford melding because materias were such a pain in the dick to get. I've crafted a fair bit in every expansion(less so in HW cause I got really turned off by the initial implementation of crafting/gathering, which they've completely removed right after, fucking favors and weekly capped scrips man) and at no point was crafting hard or challenging, the "dumbing down" was just removing a lot of superfluous shit that didn't really add anything and making it less weird with so many skills you actually never want to use.
The main "difficulties" in the past for crafting was you had to do leves so it cost a bunch of money, and you had to level every craft to a certain point just to be able to craft properly due to cross class(good luck trying to HQ fucking anything without Byregot) and so people were put off by the whole thing, but they fixed both things so it's more accessible, but these were artificial difficulties, it wasn't fucking Dark Souls when you crafted a piece of Rakshasa or Ironworks or whatever, it was exactly the same shit as it is now, you just needed more time and funds to get to that point.
I think expert recipes go the right way, in making manual crafting a thing again. Not an overly complex thing, but it's fun to actually engage with the crafting mechanics rather than just play Teamcraft for a bit then never touch it again until they update the requirements. I hope they re-use those systems next expansion to make more complex and more engaging expert recipes. I also hope they don't do the Ishgard ranking shit again though, cause that part sucked. And I say that as someone who did get the Saint title, it felt like old school mmo shit where you have to login everyday and drop 8+hours into the game to make meaningful progress, but I could do without that tbh.
