1.) No, Spacetime's drop system is the fairest system out there, based on absolute 100% luck, nothing else effects it. If theres one person in the party or 100,000 people in the party, you still have the same exact chance of getting a rare drop.

I have two questions about this.

1. Just recently, I think in this thread somewhere, I read that the more people in a group the greater the chance of a rare dropping. So, does a group with two people have the same chance of getting a rare as a group with four people, or the same chance as a full group?

2. I'm sure the part of your post that I quoted makes since. I'm just not following it. If I'm in a group with 2 players and a rare drops, I have 1 chance out of 2 of getting that drop. But, if I'm in a group with 4 players my chances drop to 1 out of 4, right? What do you mean about 100,000 people being in the party and everyone having the same drop rate?
