I took advantage of Fantasy Flight's sale of 3rd Edition WFRP stuff and bought quite and abundance of wonderful goodness.
Sorting through it brought a question to my mind though: If I have 2 (or more) decks of Wound or Disease decks, due to having a full set and a Game Masters Vault, does it create a problem mixing them?
Is there some kind of specific frequency of occurance that the individual cards are supposed to have that is ruined if you have doubles of say the base set but only one set from somwhere else?
