Wow, some of you guys really went insane with my posting. I didn't expect so many negative and insulting comments. Not everyone has the money to spend on three core sets, nor does everyone want all the extra cards for so few.
Selling extra core sets is probably not as beneficial as you'd think. If it impacts the minds of those who don't have the money to buy three sets to get the cards they would like, they might not be interested in buying further sets. Customer satisfaction goes a long way in long-term profits. It is actually pretty simple. Anyone who has taken a few undergraduate marketing or economics classes would know this.
If I am spending a lot of extra money on core sets, and I have a budget, I am less likely to purchase the packs and deluxe expansions. That means that FFG is focusing more on the original product, and that will skew some of their data. If customers are buying a lot of the core sets, but not bothering with the whole purpose of the LCG, it disrupts their models. It also means that certain sets will be under printed as the demand will not be for when they are released, but sometime after when those people can afford it.
The purpose for FFG not doing this has to either be that they don't think it will be profitable or that they worry about the print-on-demand card quality. In which case, they should just print it with the other shop, as the set will be more than just 60 cards, enough to justify the cost and quality improvement.
When I message other players in other forums, most tend to proxy the cards, with either other cards and a slip of paper in a sleeve or by scanning and copying the card. In either case, FFG is losing money, and it is making the game less attractive for those who are interested, like myself.
FFG: Unless there is a clear model on why this cannot be done, it probably is in your best interest to print the cards to even out the playing field and to clear up the proxy issues. People will pay for them. Thank you.
