It's not that hard. Atm I'm taking a bunch of henchies out to SF whenever I'm on and kill everything that moves until I'm at 60% DP. Then I just warp back to Deldrimoor Warcamp and sell everything I picked up. Then I do it again.
This way I can make loads of money in a short time if I need it. For example, I made 6k last night in about an hour and a half so I could buy a new suit of armour (Necrotic). I'm hopefully gonna do the same tonight so I can buy the Tormentors Armour as well.
I usually sell to a NPC. When I finally get another green item though I'm gonna flog it for what it's worth. I can get up to 40k on some things...and I've seen people offering to pay 90k-100k for items they can't find.
ON average I can probably get around 15k, 20k max.

If you're gonna go out farming, go out on your own with henchies, not other players. It may be that bit harder, but at least you get all the items that are dropped.
? Henchmen get drops just like players, it's just that you dont see them. Playing with 5 humans or playing with 5 henchmen doesnt make a difference concerning drops. Otherwise what would be the point in farming solo.
High quality items will drop with more people in the party. However, the items may go to someone else. You can solve this problem by going with all henchmen, letting them die, then farm away from them.
