Firstly, I love the lore in the ES series, and I do not know how I could play ESO not biting into it as deeply as possible.
But I have a problem which plagued probably many other players. When I was a low level player often chosed a LFG system to came across players. Often they had no interest in the lore or they just rushed through the dungeon. Often, for this reason I also had to skip lore. Now I would gladly redo low leveling caves just for the story. Unfortunately this is not possible. Once finished the quest can not be repeated and lore from NPC talking is gone. But there is for me little faint glimmer of hope. Not so long ago Devs wrote that the they are working on changes in dungeons system which would allow adjusting the level of the cave to group leader level. So the question is would you like (together with that changes) to see the ability to redo the quest associated with the story in a dungeon? Of course, a reward for re-finish the quest cant be skill point but only a random item or same gold.
