There are probably quite a number of us from all three factions who have wondered about this problem.
In the most recent merge it seems a number of servers became imbalanced either because the newly merged players were mostly of one or two factions.
If there were some creative thinking about this type of occurrence then perhaps a way could be found to offset imbalances in general. After all if one or more factions become demoralized we simply see what was occurring soon after the game’s launch.
Players in much smaller factions simply migrated en masse to another server. This left quite a few servers with one of their first tastes of really being emptied. This serves no one’s best interests.
