You would lose money since the price is dropping in the GE currently. It won't sell at 908
Don't make that assumption, as it would take long for 1-99 mage, the price will fluctuate all over by the time you're done, who knows.. You could make money doing 1-99 Mage, by selling the air staff for more once you're done.
Anyways, this would take forever, however, it is good for lower levels that are just starting off.
