I can understand not wanting to be forced to que for hours trying to run a dungeon to progress in the story, a possible idea would to have all the story dungeons solo then once you complete them have a hard mode which is essentially a group version of the same dungeon which is entirely optional, problem is it Pratically involves making 2 dungeons for one instance with all the scaling and difficulty tweaking. I personally don't mind running dungeons to progress in story I DO mind however getting partied with idiots, wannabe elitists and waiting for hours in duty finder (the bane of being a dps class).
