Man, the more things change the more they stay the same.

The simple fact of the matter is you've had 90 levels to learn how to do mechanics and recognize the very predictable patterns in how fights progress that have maintained relatively the same for over a decade now. The game is capped at level 100 now, content is going to be designed at the difficulty of 100 levels progression and iteration, and there's really nothing you can do about it. Friction in games is good. Failing and learning from those failures is good. If you're terrified of loss-states then don't play games with them. This is a conversation that gets had in Literally Every Single Online Game That Makes Hard Content, and to be quite frank it's getting extremely exhausting.

If the content is getting too hard for you, then you have tools at your disposal: if it's MSQ content, then let your trusts literally show you where to stand and follow them around. They do mechanics FOR you. If it's stuff like Normal Raids, then you're in there with at minimum 7 other people, just say ahead of time "/p Hey I'm struggling a bit here so please be patient with me, thank you <3" and 99.99% of the time people will be completely fine with you face planting and if the group wipes, will give advice and pointers if you ask for them, especially now when everybody is still learning the encounters. In a month or so, the majority of people will have cleared and will be farming for tokens and tomestones, and then it becomes content you can just follow other players around in to clear 90% of the mechanics you'll be facing. If that's STILL too much for you, then wait until IL increases and then go back in and clear with much more forgiving stats. At that point if it's still just too much then just have the courage to tell yourself "yeah I'm at my limit haha" and do other content until the game advances and you can go back at IL cap in the future.

Friction is good. It keeps things engaging. It provides a sense of meaningful progression not just stat-wise but as a player. When something that gave you trouble no longer does, you feel that and it feels good. FF14 has been missing that friction outside of end game raiding for a long time now and to see it back finally is a joy.

I feel for people who are struggling, I really do, but your convenience should not come at the expense of the game's content and I urge you sincerely to not give up and keep trying until you get it, because when you finally do you will feel like a god.
