Are the point disparities based off of how easy/shorter the older raids are than the later entries? I kind of find it ridiculous that the ARR raids give less than 400 while the Nier raids award between 800-999. I've never bothered to time them but do those raids take over twice as long as the Crystal Tower series?

If so, then I can maybe understand that, but it still feels a little disappointing when you load-in and find yourself in one of the ARR ones.
