if you think about it, farming for 6 hours in most mmos doesnt get you what you want.

for example before i quit rs, i had a friend who wanted a certian drop from a certain boss (corp)
he had been "farming" it for over 200 hours and only had recieved small, worthless drops.

but then again.....

another player got a divine after 1 kill and like 10 minutes lol...
(divine=570M in rs gp)
570M in rs gp= $600 USD)
