Since the problem involves most of the current LCG's I didn't want to post it into a specific LCG forum.
Most of you guys know the new problem which came with the new LCG format: There is no market for single cards.
If you want an additional set or more of some basic cards almost every deck/several decks need, you have to buy a second pack/expansion (If it's in the new format) or 2-3 packs/expansions (If it's the old format). So, you paid about 20$ or more for 3 cards and get 57 or more cards you actually don't really need. Of course, it's cheaper than some single Magic cards, that's a great start but there's still some room for improvement of the customer friendly LCG concept.
Well long story short:
I want to suggest a yearly expansion pack (20 different cards in copies of 3) designed by the game community.
People will send their card suggestions per mail to FFG until a certain date is reached, then FFG will post a poll with the received suggestions and everyone can vote for their favorite cards.
