So, if you want to be amenable to roamers you need to not have the guild cap at an arbitrary number like 5, and A. Allow many small guilds to enter in alliance B. Do it strictly on (most likely active) population, not guild #. C. Perhaps allow small/roaming guilds to accompany large guilds in a different quota. Roaming culture can be a lot more server based than others, and as the system is proposed I see no way small roamers are going to have their guild accepted into the alliances all their friends zerg in. This system is preferentially dividing based on guilds that are incentivised to run larger (guild cap) and group with others that run in tagged organised squads. This system means that in general, you need to carefully select the guilds that will be the most beneficial to large-scale ppt in order to be effective.
