As group of the #1 server we have everyone donate a minimum donation amount of 200k coins a day. If they do not meet the donation requirement they are automatically disqualified from GNW packs "assuming they made all 4 anyways". We are group level 11 and are about 750 daily activity points. I suggest you start letting in low level players are the group activities can boost your groups activity rate to get you upgraded faster. I usually take 1-3 for 9tails and the coins reduction hurts. I my self only donate between 500k-1 mil a day.
