ps: for the epic ground mount, and the normal flyer, the quests to 70 will give you enough money if you don't waste it, so you do not need to farm for it.

Also, farming motes is good, and you can buy them from the Darkmoon Faire for almost nothing.

Oh God I must have typed this a hundred times now....
(I know you are being sarcastic, don't need to tell me)

EDIT: Buy 5 people epic flyers? Wait till the next xpansion to gear out your Deathknight, I guess...
