I think people who are expecting Dawntrail to refresh the game and make it seem like new again are going to be disappointed.
Thats one opinion, sure, on the other hand we dont know. From the trailer ( this will be one of three or so, as we havent seen the FULL trailer yet ), IMO theres no need to borrow disappointment. Ive enjoyed Endwalker immensely, yet whilst I agree that to a *point* it has been..well..formulaic, theres always room to see things changed up.

There will probably be new bits sprinkled in, but dungeons, trials and raids will all be like what we have already been getting and that is the content that we interact with the most.
Not too sure I agree here, raids have their appeal, yes, but in looking at the ENTIRE picture, no.

There are a myriad of other activities that ARENT raiding, and have their own appeal. FF 14 is not and never has been 'raid centric", I think that if you had complete participation data ( which we dont have and never will ) you may find that perspective covers a much wider scope.

"If you dont raid you arent playing the game" is a narrow and idiotic stance.

Im happy to wait and see whats coming. That comment I saw about "maintenance mode" was kinda funny, as I KNOW we will be seeing a broad swathe of new content added over time. "Maintenance mode" and new content dont go together at all.

We have two more Fanfests and a lot more detail pending.
