Whenever I am in a dungeon group I always find it that people never have the time for fellow players if they want to read/listen to the dialog of the NPC quest giver. Some stages of the quests require your entire party to listen to an NPC but others are individual. I do enjoy this very much and I always listen to all the dialog but so often find it that other guys think I am "afking" or "wasting time" because they just want to skip through and "just get it done with".
ESO has done a wonderful thing giving dungeons fully voiced and interactive quests and we should appreciate it. Why not go one step further and make it that we cannot skip through the dialog (at least the parts that matter, that update the quest and tell you what needs to be done in order to complete the quest). Or make it so that the group leader clicks the appropriate dialog lines and the entire group listens to his dialog. If that cannot be technically implemented then I am a milkdrinking Nord, mad as a box of frogs.
What would it add to the game, the pros and cons.
Pros.: Pretty much read above. This system would allow people to experience the Elder Scrolls way of gaming, to appreciate what the game developers wanted us to experience.
Cons.: Some people would complain that they are wasting their time. Inded that would "force" you to spend 3-5 minutes more of your precious time inside a dungeon.
