Are you sure about 4% base chance for GF Cards and 8% for boosted? This leeds to a distribution of 1 maxed GF every 4 maxed RF.
Is there also a guaranteed GF of Airdrops amount when using Alchemy potions? 12.5?

I listend to the Town Hall and you said that you want to be free to adjust the Entries for Guaranteed Airdrop. I fully understand the good intention behind. But on the other side, players want to plan their conflicts and want to be prepaid. The biggest problem Dave mentioned would be, if there are way less than 3000 Airdrop Cards, because a lot players could let their BF cards work on land insteed of participate on conflicts. So it is more a problem to the downside.
Here a suggestion. Why not making a pool of 3,000 Cards? If at the end of the conflict there are less than 3000 guaranteed Airdrops, the chance to get a Card will be increased from 0.125% to a value that fits to the 3,000 cards? e.g.: only 2,000 garanteed airdrop cards: the chance increases to 1.875%.
If we are short on conflict contribution, the higher chances give players an incentive to use their land workers or buy more cards -> win-win
If there are way more than 3,000 airdrops, its a sign that there is a big participation in Conflicts. If you say someone who ownes 111,111 CP has deserved one CC of all airdrop cards, the 800 could be flat until the end. At the current prices this is at least 550$ with the cheapest off-meta cards. That gives planning security. -> win-win.
What do you think about fixed pool + adjustable chance and 800 entries flat over the whole conflict season?
