Reconsider Deeply Volatile x4 Quest

I can understand the motive behind is to spur the player to improve and find better approaches. But it can be done in other ways. Take for example, I don't remember MHW having such kinds of stringent requirements on their MSQs. You can put more loot drops behind tougher challenges. And this 4x quest literally locks you to complete all 4 deeply volatiles before you can actually choose to help others in earlier deeply volatiles because they don't appear in your map only after you've cleared all 4. What's equally bad is after completing this quest, your next quest is laharback, which is ALSO behind a 20minute timeline. Don't they have recondite missions with stringent conditions and better rewards??? Why can't those quest designs be like this? All this seem to indicate the late game quest design quality actually took a downturn to roll out the game ☹️
