And IMO this is another rule that should not be enforced by anyone who isn't a FFG employee. Assuming the card proxies are accurate copies of the real card the no-proxy rule provides absolutely no benefit to either player. The only benefit is to FFG's profits, and I don't see why anyone who isn't a FFG employee should feel obligated to protect their profits.
It isn't a matter of protecting FFG's profits.
FFG produces a game at a price they think is fair, in a structure they think is fair. I pay that. At no point does FFG's profit margin enter my brain - it has nothing to do with it, and I think you know it.
It's a matter of respecting the people who make the game, and respecting how they ask people to play it so they are compensated for their work. I don't play the game with empty bases, Litko firing arc tools and home-printed cards. They produce the game, I buy it and play it as they choose to sell it. I don't always like the way they do things, but if I dislike it that much I don't buy it.
<shrug> Call it as stupid as you want, but I fully expect that everyone will settle down once it's actually out. All the wailing and gnashing of teeth will trickle down to just a handful of people who want to run an 8Z swarm and will grumble about not being able to do it, and despite all the swearing that they'll never do it it'll settle into the same place as printed cards - an occasional pointless grumble that nobody really listens to.
