To me, immersion in questing means knowing as much as reasonable in the context of the quest, whether you get a quest marker or just written directions.
If it makes sense that the quest giver knows the cave where bandits took the sword they stole from him, then the quest marker should take you to the entrance of the cave and have you explore the cave itself to find the sword. If he (for some reason) knows the specific stash box where the weapon is stored, the marker should point to there. If he only knows the general area where the bandits have their hideout, then that should be as much as you know. The marker shouldn't take you right to the "stash box" for every single quest, especially if that "stash box" is a moving NPC.
The quest markers themselves aren't the problem, it's that they just don't simulate what you should plausibly have for directions in each quest.
I know that many others do like how Oblivion and Skyrim point out quest goals so specifically, and I wouldn't want that changed just because I don't like it myself, but it would be nice to be able to choose between that and markers that reflect how much the player character is actually told.
