I have seen all the (beautiful,magnificent,lovely,awesome,etc) artwork the blizz artists have created for the zones. I outgear every mob except bosses in the zones. The only reason I want flying is to save time running from one spot to the next, where blizz purposefully puts a dumb little fence directly between point A and B so I can't just auto-run while I go grab another beer. Those one or two minutes add up to hours of purely wasted time (but increased profit for blizz) and increase my frustration because it isn't necessary. I get the whole wait-until-you-see-everything-for-a-few-months concept, but enough is enough.
