Sorry I disagree, the quest always tells you at least which city or hold, without the quest marker highlighted, you do not know exactly where in that city. It may just say a person and a place, you could encounter them at their work, on the street or in their home. I feel some people get blindsided by their misgivings.
This is what the CK is for, don't like it, then knock yourself out and go remove it!
I think you fail to understand the fundamental issue here.
The game is not designed to be used without quest markers, and quite contrary to your claim, many quests simply will not provide you with any directions whatsoever, often not even the name of the dungeon youre supposed to go to.
Secondly, the CK is not available to over 70% of the people that play Skyrim.
Therefore, it would be no more than logical to request a more immersive way of playing the game for the next iteration of the series.
The problem that I and many others like me would like to be solved can be done so quite easily by a shift in the premise when designing the game. Instead of designing it for use of quest markers and then add an options that allows you to turn them off, make a game with good and detailed directions and
then add quest markers to them, with the option to turn them off.
