Short answer: Casual game.

Practicly all content tied to the main story has been easy to allow as many players as possible to be able to proceed somewhat painless thru said story.

The more difficult content has been side stuff like extreme primals or coil raid.

And imo it should stay like this, sure they could toss in a side dungeon not tied to the mainstory once in awhile and make it harder but anything related to the story should be easy otherwise all your going to get is another Steps of Fate rampage.
