There are so many factors that are contributing to this...

1 - The first one is hunts. Queues have been severely damaged, if you are a tank or a healer it's not significantly noticeable, but if you are DPS it is. Also, they've trivialized everything.

2 - Atmas. I've gone through it, and not just once, but it saddens me how SE is deciding to go this line. SE doesn't understand that the majority of people did the Atmas because they hadn't a choice (despite most countertrolls think by saying "it's optional") but because the desire to get their next tier of their relic weapon was higher than the amount of boredom they had to put up with all the atma horror story.
