Looking at recent suggestions, I think it would be a good idea to take the least active server, move its players to another one, and turn that vacated server into a dedicated base-PvP server. The others would remain for "PvE" farming—resulting in three servers for idle farming and one dedicated solely to PvP. However, this would require a system to transfer characters between servers.
I assume we don't have this system currently due to server capacity limits and the lag that would result from having so many people on a single server. You would need a higher-capacity server if you want to expand the community or consolidate it to create a livelier game environment with more activity—since there would be multiple clans per server fighting for bases.
Another point is limiting guild size to a maximum of 10 members to prevent monopolies and encourage alliances; currently, clans can hold 30 members, yet the total player count per server doesn't even reach that number, leading to a monopoly and a lack of PvP action.
