I agree with this 100% and the reason I think this should be the focus is that it takes your mind away from the grind. Lets say you and some friends are mid 30's and you run a dungeon a few times per night most of the time you're having so much fun you don't even realize you gain a level. With leves and grind you are constantly reminded how far you are tnl to the point where you feel like you make no progress.
