That's for just dungeon/raid/trial content.

Crafters are an entirely different beast when it comes to this. Then there are the House owners and the RPers.
I wouldn't say casuals do Extremes. Extremes as "casual" shows probably you are harder core and view these as super easy for the people who play sporatically and aren't that invested in the game, or just like chill content.
