Even with a flying mount it would not be much difference for me. Every single pixel of Pandaria contains 10 quests.
The questing is way too boring, pick 10 mushrooms, kill 15 insects, save 10 pandas, repeat 100 times per hour.
I think one part that makes this boring is the 5 lvls. When we had 10 levels it felt like we were progressing but now its just depressing being like "now i did 50 pick up quests... oh great i filled 3 bars."
