Thats what a lot of the GD forum regulars want, so they can have just their M+ 24/7/7! They do not like leveling, dailies,raid,PvP, the list goes on. They think everything, and every one should be doing M+ runs endlessly, because to them, it is what the new WoW is all about!
Truthfully, they are not wrong, because Blizz refuses to do anything for the solo players, even though Ion said they were. I would love to see M+ in a queue system, to a certain point, even if it were just to a M5 key.
