You can do solo Khitai: http://aochideout.blogspot.com/2011/...uests-max.html
This guide is slightly out of date (you get BETTER rewards now) but even back then you could go around 300 MOAs and 2 gold per hour with a chances of blue drops you can sell on trader (getting loads of bags).
This route will benefit you character in every way (mastery, renown, items, MOAs, Insignias, reputation) and make you money at the same time. I highly recomend this.;
