the average hearthstone player wouldn't bother making a deck even if they did offer a free ticket. and still, most players would be lucky to get 2 wins.
I feel like a free pass is totally justifiable, so every player could at least get their single pack for the week.
Also I think it's hilarious that you don't even come close to making your gold back unless you go a full 12 wins lol. The people who are capable of getting 12 wins don't need the packs and dust.
