Lack of End Game Content

Very fair and completely agree. In the end it's about effort vs revenue.

I do believe engaging endgame raiding to be important because it feels like horizontal progression on the main piece of content. I'm personally from the mindset that quality > quantity, especially in the replayability value department.
I also see XI mentioned a lot, but I'm afraid I do not have any experience with it to know how it properly compares.
