You forgot something: Impossible mission- A guild needs to get the whole map, then the faction of GMs will attack you, protect all territories for a month.
I was thinking, and honestly I hope agatio agrees, that we have 3 monthly map resets, to keep the map from being too dominated by one faction or another.
3 months ~13 weeks...15 weeks sounds better, cuz 15 sounds more smooth
That could easily backfire though, because people would just kill the small ones for a guaranteed victory.
