Cannot agree with you more. Though the idea is good, 20 packs (~3 USD) honestly is like a peanut. Since it's a competition and there will likely be 1-2 winners, why don't they make the prize more attractive? It's more fun. In addition, ultimately Nordeus still will benefit more since participants will tend to spend more packs for it.
