The reason FFXIV is lacking content is because of casualization.

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.
