I have been on My friends warrior(60). Lately I have found that ppl will pay pretty good money for you to do solo runs for them. So just stand in SM and get in /4 Lookingforgroup and make a macro.
/4 (your class & LVL) I am running people thru SM any 2 parts for 10g.
you should get about 2-3 whispers
ok now you have made 10g and plus coin drops so you should have made about 14-15g.
you can make about 6-7g per run if you solo it and pick up all greys and up. (this is with out AH greens and rare BoE blues---Recomend AH those tho
