Right now the only thing you can do as a guild is GvG which rarely if ever breeds a good feeling in the community. If there were some sort of mission, point system (like levels run), or hell... in Dragon Saga you got like a 5% bonus to damage health etc for being in a guild for over a month, +5% for having your guild be active in a certain time (we could use prestige for this). Maybe a heat/crown bonus for having a member you invite stay in the guild/be active for over a month?
