ahaha, over 30 people in my guild allready have their epic mount. A friend of me has 2 lvl 60s allready and both have epic mounts. Aoe farming easily gives you 70+ gold per hour. That's just 2 days of playing for the average wow nerd.
I did nothing but farm scholomance yesterday and got 3 recipes worth over 200 gold, that's 600 gold allready, just from farming some instance...
The difference between the average player and those ahead of the pack is huge.
There are BoEs that are worth (and actually selling) for 500g+, edgemasters, freezing band etcetc, some enchant recipes (9 str) are selling for 500g+
