Lack of End Game Content

[DevilsDontFly]

It's not rushing when you are just playing normally. If you have the time to play 16 hours a day, why not? Should I play only 8 hours and sit the other 8 hours here, doing nothing?

Rushing is when you skip the cutscenes and just run from quest to quest without reading the story.

While I agree with you, there's no amount of endgame content that's going to last for someone that can play 8+ hours a day every day, rushing or not. It might be sad but the truth is that today's gaming design is aimed at the concept of "people don't have enough time in their hands to do stuff". That's why MOBAs and battle royales became so popular over the majority of MMOs.
