I have only cleared a pair of savage fights before, when I feel up for it. I otherwise have more investment in the casual content. And yet I fully agree: most normal content, especially nowadays, is incredibly easy.

I rather enjoyed Shinryu's level of difficulty when it came out, because I hadn't seen anything mandatory demand so much attention. It was honestly refreshing for me... but other people certainly disagreed at the time, with many people asking the fight to be toned down.
I absolutely loved Orbonne because of the more demanding fight style with mechanics that required group coordination, know-how and realizing there were more details than just "lol stand on the place".
That's why I liked POTD back then, because doing deep dives with my friends was so fun. We had to coordinate, we had to be careful, we had to know mechanics, we had to figure ourselves out whenever stuff went wrong...
It's why I loved stuff like Dun Scaith or Ozma's fight.
And that's also why I like CLL, Dalriada and Delubrum Reginae. Because they were casual content, yes, but they didn't hold your hand all the time either like the majority of the dungeons do.

Sure, you can argue "well, everything in the game eventually gets easier through repetition". But I'm talking to things that, at least for me, posed a bit more of a challenge at base than the rest. Certainly nothing to the point of a Savage, but also requiring a bit more coordination than most other fights.

To me, the Crystal Tower raids are absolutely boring.
Euphrosyne is really, really bland apart from Halone that at least tries to be challenging.

I like to tryhard. But I know several people don't, and that happens to be the demographic SE pays attention to. Because those people are the ones that are subbed into the game, take their time with content and just want to chill and explore.

So... yeah. I'm not a raider under any stretch, I'm as casuul as it can get. And even then I think we're getting stuff that's honestly pretty easy.
