Item quality and multiple players?

MF is averaged in multiplayer games, so I expect the drops to be a bit worse. But if you are able to work together, the faster killing rate may help balance things out.

Well if the majority of people aren't running with MF, adding one person who does have a bit to a 3 or 4 person game will make the drops better for everyone, except the person with the MF. So now you have 3 people who actually see better drops vs one person who is getting slightly worse and may not notice.

MF being averaged is enough to make people think drops in MP are better (or worse) than in single player because your MF will change in multi unless everyone has the same amount.
