So I finally got around to combining all of my WFRP stuff now that the Guides and Vaults are out, and to be honest I am bit overwhelmed with the sheer amount of stuff. I am in the process of organizing all of it in a nice carrying case, but I got to thinking...
For random draw decks that have some impact on play, Wounds, Insantity and Miscast decks mainly, what is the thought about combining decks of cards from different sets. That is to say, let's say you own both the Core Set and the Game Master's Vault - do you only use one of the Wound Decks (70 cards) and then add in the cards from the expansions like the Adventure's Toolkit? Since the Core Set and Game Master's Vault decks are identical, does doubling up the deck have any impact on the game other than making the additional cards added from the expansions slightly rarer?
What about having two Wound draw decks, one for the Game Master and one for the PCs?
It all seems rather flexible and a deck of cards is even less random over time than say a chart you are rolling on. I can't see why you couldn't just use everything.
