So the new Vale of Eternal Sorrows area in Pandaria is very pretty and black and stuff, but I personally would appreciate an option to revert it to before 5.4, in the same way that you could talk to a Bronze Dragon to change Theramore to the way it was before it went boom.
As someone who wanted to do Klaxxi, but never did Golden Lotus until after 5.4, I can tell you it is awful. You only have a tiny area with 5 quests that will give you rep, so it is very slow. If you could change it to a phase so that you could see the original Vale, you could do the mountain of dailies that were there and get the reputation a lot faster.
What do you think?
