Thank guys for responded, I just asked him again and indeed his main reason for not recruit new members is because it will be harder to plunder. About GNW packs, I think he created a pretty balanced and fair system. His system is based on points calculated from : Weekly group contribution * 2 + Weekly donation * 2 + GNW participate time * 5, he will give packs to top 10 players with highest points every week. I don't really want to leave cuz the reason behind his actions are kinda on point but how should I convince him to recruit new members for cross server gnw?
P/s : I don't think I can join another group and beat his behind, all pay players are with him and he is really strong by himself :P
