Some of my favorite things to do is questing and achievements, but at max level you one shot everything - and the current leveling system while questing (1 to 60) you level too quickly and leave a zone well before you’re through all the quests (especially when paired with the odd dungeon/BG).
I think it would be great if there was an option to scale areas to your max character’s ilvl to recreate the challenging environment in the questing areas throughout the game.
