You're kidding?
Isn't it a safe assumption that at that point, that when referring to "description" that we in fact cover all quest description types... description, detailed description, super uber duber detailed description, video footage or escort?
... ok, enough of the funny.
In the end, there are some people that simply don't need them. While there are others that want, need or even rely on them to advance through a game. All that being said is that there are hopes of an option to toggle. In fact, every single aspect of the UI, HUD or in-game notifications and/or tells should be subject to turn them on, off or remain hidden until triggered by something akin to attribute level or activation.
Priorities to being as detailed as they want with the descriptions have nothing to do with it, IMO. Just toggle the element, I'm a big boy. I'll figure out where to go.
