The reason FFXIV is lacking content is because of casualization.

Mobs have abilities? I haven't had to even think about how to manage mobs, stun, sleep, focus down anything in particular in.. 5 years?

Scratch that, I think there was a pair of mobs I had to pull apart 2 years ago.

(Boss mechanics, different story)

There's a mob in Amaurot that will tether to the healer that will kill the healer's ability to keep up on healing if it isn't focused down. It isn't as much of an issue now because of ilevel but it was debilitating when Amaurot first came out. But more teams used to pick up on this and would focus that down. There's a mob in Dohn Mheg that will buff another if not stunned. There's also True Bravery on Hermes in this expansion that can cause issues for the group if the tank doesn't interrupt it. And any succubus mob doing a Beguiling Mist that can be interrupted, like in Mhach. Not interrupting that can wipe the entire raid even now. And there are the mobs in Puppet's Bunker that paralyze the entire raid if tanks don't stun them, which they usually don't. Not as big of an issue now but it had an effect when things were current. Not enough to cause a wipe there all the time but everyone getting constantly interrupted from it didn't help clear that area quickly.

There are mobs in dungeons and raids that do straight line AoEs, circle AoEs, and donut AoEs all in the same big pull packs so the tank has to be cognizant of how they group these. Or just grab everything and let the melee die. That's pretty much what happens in Euphrosyne with the adds in the ice area. The donut that should be safe is usually completely covered in other AoEs.

Plus, you have done the Barby trial, right? We may not need to stun, sleep, or focus down anything in particular but we definitely have to think on our feet in that.

Sleep is really the only crowd control ability that doesn't see some use somewhere.

Yeah I mean I get they exist in general. But it's never been a real problem, even day of. We're designed to be able to basically brute force through everything with AoE and overheal. Unless of course your comp was SGE + GNB* day of, then FML. lol
(Again only strictly talking about Mobs/Trash)

It just doesn't compare to a lot of the decision making we need to do in other MMOs, or ARR-HW of course. And we can say that's good or bad depending on who wants that type of content. But ultimately it just is.

I don't deny we have to think in some content, mostly boss mechs. But I literally try not to do any content with trash anymore, because I fall asleep. :/

I almost wish we got rid of it altogether, or the trash phase in dungeons were shorter. Because they're not enjoyable. They did right by the trash adjustments in Alliance/Raid.

The tether in Amaurot was. Once we figured it out and that mob got focused down, groups didn't have issues. The boosted Dohn Mheg mob could also delete your tank's HPs. I mean, we know these examples because we learned to watch for them and react because they were impactful.
