Ich hätte wohl noch mehr aus dem Forum zitieren sollen: The actual items are then created only once they have been looted to a character.

Loot tables will work something like this:

Loot Table 1 50% Item 1 30% Item 2 20% Item 3

Loot Table 2 50% Item 1 30% Item 2 20% Item 3

Loot Table 3 50% Item 1 30% Item 2 20% Item 3

Faction Loot Table 50% Item 1 30% Item 2 20% Item 3

The Master Loot table will be 100% Loot Table 1 50% Loot Table 2 50% Loot Table 3 100% Faction Loot Table

As you can hopefully see, if you wanted an item in loot table 3 you would have the % chance of that loot table being used then the % chance that that item from that loot table drops. There will always be a faction loot table to differentiate between horde/alliance loot for things like Shammies and Paladins. I hope you can follow that...
