This was given by a guildie of mine, and I think its a great idea.

You take the number of party members doing the raid and divine that in half. Then put that number, below 1 and thats you chance at getting raid loot (per person). So for instance:

Number of people on raid: 4
4 divided by 2=2 so you have a 1/2 chance at getting raid loot per person. Which means that an average of 2 will drop. 50%

Number of people on raid: 10
10 divided by 2 = 5 so 1/5, meaning an average of 2. 20%

This would be changed into a percentage, this is important especially for odd numbers because a 7 person raid would give you a 1/3.5 chance, hard to do that with fractions. So everyone would have a 28.57% chance at getting loot.

Any ideas, comments?
