Currently out of my 5 accounts only 2 have the expansion on them, still need to buy a 5th copy so that all have them. so for the time being I am using my 70 (Almost 71 Pally tank) with my other 3 accounts that do no have it and just do dailies, I get done with them in like 30 minutes or so. So I am making 100g roughly in 30 minutes on each of the 3 shaman and like half that on the pally tank. When I pick up the other copy then I will go North, already have my epic ground mount and my flying mounts on everyone so really only thing I need to worry about once I go north is my Cold Weather Flying mount.

Oh and you cant use the mammoth in old WoW at least that is what they where saying all along I am not sure if this has changed.
