It's so funny to me that yoshida waited an additional week to release dawntrail because (in his own words) he wanted to give players time to enjoy the elden ring dlc, but he couldn't hold off a week for chaotic so people could enjoy christmas. But that's unrelated to OP's complaint.
In my mind this is just more "busting your balls in pf until your whole team memorizes the thing" raid content that I'm really not into. This standard of difficulty where you just waste hours of your life "until everyone gets it" isn't enjoyable to me and honestly never has been. It's only gotten worse as the jobs have become more robotic and standardized because I can't even enjoy playing my class while running the content back. I haven't logged on in weeks because there's just nothing substantive to do outside of that tier of content and there hasn't been in months; it's just been savage and ultimate and unreal and now this. This chaotic thing could have been a cool way to revive old alliance raid content that people avoid due to level capping. Imagine fun stuff like dun scaith or orbonne, but now you get your whole kit. Alliance Raid (unreal) style, or something. The difficulty could've been a nudge above normal but below extreme, serving as the buffer zone between difficulty segments that many players have been wanting for years. The rewards could have been high ilvl stuff for people who care about that, as well as dyeable versions of the undyeable armor sets that people love from these alliance raids. idk, maybe it's too simple or would've felt recycled. I can really only speak for myself when I say that reviving old content and making it enjoyable in 2024 at a difficulty level that felt approachable to everyone would've been more enjoyable than yet another single floating lady boss fight in a floating void arena that you get to "prog" with 23 strangers until most of them stop dying to the same thing over an hour in.
Not even saying "don't do it again" because I'm sure there're people who love this stuff. Just, there's a really clear 2-tier difficulty system in this game that needs to be addressed. You're either falling asleep in normal mode, or you're busting your balls in pf until everyone learns the synchronized dance. For people who fall in the middle of that, or don't really find themselves enjoying either type of difficulty (hello), there just isn't anything to look forward to until next year *maybe*.
