Now, do you know any other company, any, which keeps releasing substandard, overpriced products, yet customers come back for more? Failed casts are not and cannot be a surprise anymore, yet I hear this all the time: "Man, I got trash from them again".
Again? Why don't you do what you do with any supplier of faulty products and services - change it!
That's the power of Games Workshop. You will come back for more.
