Backround Info: the target is Razorfen Downs located in the southern barrens, this instance is for about levels 35-45.

To do this run you need to be a rogue lvl 60 (maybe a bit below) and you also need to have enchanting
When you enter the instance go into stealth and follow the map outlined (it may be a bit incorrect but u get the idea, just get to the last boss)

When you get to the part labeled 4 look around for the boss there (he is hard to miss) and kill him
he should drop a blue item, next go back into stealthed and travel to the top of the spiral and get to the main boss of RFD.
the way to kill him is to keep your back to the little cave like thing that he stands infront of other wise you will get knocked off the mountain.
start out with cheap shot to stun him and just start spaming skills, once he summons he minons use evasion. (you might want to bring some healing pots just incase)
if done right he should die and drop 2-3 blue items

now comes the money making part
you should have 3-4 blue items in your bag now and this is were enchanting comes in. use the skill disenchanting on the blue items
the should all disenchant into small radiant shards which sell for 10-15g on my sever.
once you get get at this it should only take about 10 mins to complete which is about 60-90g per hour PLUS sometimes a green will drop along with blues which could also sell on the AH
i suggest selling the small radiant shards for 10g so that people will chose yours over others and selling them in stacks of 1 or 2 will also increase the buying rate.

PLZ reply to this and i hope it works for all rogues sorry to other classes
