Max team size of 5
For GW how about a maximum team size of 5? With an option for a Guild to field multiple teams if they have sufficient players. It would allow smaller Guilds, or those with members in multiple time zones, to get into the fight without the risk of facing a team of 10. I also think it may help with matching teams with similar player levels against each other. The points would still be available for the larger more active Guilds as they could deploy multiple teams.
