Has Blizzard specified how they do co-op MF drops? I know they have said that item drops, as well as MF%, are player-specific. However, this still leaves ambiguous the way that item drops work for killing monsters. For example, if two players are in a party, and one player does 100% of the damage in killing a monster, do both players MF trigger on that monster? This could lead to all players in a party sacrificing health/damage to stack as much MF as possible, and the last member doing all the work (or one high MF weakling just following a strong party and getting lots of free items). The other scenario is actually even worse, where only the killing player's MF triggers on that monster, meaning that you would only get item drops from monsters that you deliver the kill to even though you may be contributing significantly to the amount of damage deal to all monsters (like with Static Field, Meteor, or poison effects). How does it work?
