When we move to Unity on the live server there could be an opportunity to address the issue of inactive accounts held in guilds.
If a player is unable to make the move to Unity why not remove them from the guild they are being held in and retain the account on the system for when they happen to come come back to the game - if they ever do. Most games totally delete accounts after a certain period of inactivity but that is not what I am suggesting - though I do think BB should consider that anyway.
By doing this BB would show the true number of members in each guild who are actually playing the game, guilds would shrink in size and may therefore encourage mergers leading to more chat and social interaction in the new guilds.
BB could even be totally radical and delete all of the existing guilds so that we all have to join a guild again.
PS My guild currently has 50 members, 48 active. Be interesting to hear the figures of other guilds, especially those against the idea.
