Multi-questing is the problem
 

If we trace back the raid rotation/sharing problems it seems like a huge portion of the motivation for the greed is because of the ability to sell rare pieces.

I am in a small guild and almost everybody I know who has an epic has had to pay extortionary amounts to large guilds for their rare pieces.

Cut out the multi-questing and I suspect there'll be more willingness to cooperate and share.

Not MQ that is the problem. It's Greed that is the problem.

Well you can't make people less greedy.

All wrong.

Supply isn't satisfying demand is the problem.

and what exactly are those players going to do with those millions of plat (=pixels) in their video game bank?

its not greed, its something else.

Greed can be ingame or not

dude wake up. i just did a quick google search and found a plethora of RMT offers for p99

They'd still cockblock and just force people to pay for loot rights. That would have to be prohibited behavior as well.

Mobs could drop nothing and people would fight over who gets to kill it.

You can't code in a way to stop RMT, but you can code in a way to stop MQ.
