there should be no limit in packs and leader should not need to give them. if one join 2 round of gnw he qualify for rewards. 2 round participation gives 2 seal, 3 round participation gives 3 seal, 4 round participation gives 5 seal, 5 round participation gives 6/7/8 seal. kinda like this. other reward per round like group point and contribution ok. those who says leader should make a system to rotate pack- 'leades not getting paid by devs to manage group lol. they also here to play game and enjoy not to do office work for devs and guide group members to spend money in game'
