Yep, you're right. I am sleeving my cards so I wanted them in full size so they fit well, that's why we went through that trouble. When I print at home I simply print fronts and backs on separate pages, cut and sleeve them together. But this game deserves better quality than my home printer :)
That is fair. I asked for A4 on one of their other games but just got replies like it doesn't matter that the size is smaller etc. But I still sleeve the pnp cards to help protect them and make it easier to shuffle. And then the sleeves are way to big.
So I didn't know if e are going to get A4 anytime soon. If you can be bothered going to the effort you can cut out the cards and recreate a file using this: https://boardgamegeek.com/thread/3662088/new-pnp-tools-card-formatter-and-card-e...
