Implement maximum cap on number of members per guild
To have a maximum limit cap on number of members allow to join a guild, example: 60/80
When implemented, all guilds will start with a base limit of 40/50.
This will help to encourage smaller guilds to be formed together with the reduced guild upgrade cost from lvl 1-5.
Reducing the possibility of a guild having a massive dominance all over the maps.
Reducing the possibility of a guild causing balance issue if transfer itself to other town.
Reducing the possibility of a guild equal to 1 town population.
Cost to upgrade slots can be implemented using new points system that can be earned through the events such as Heldenian Siege/ Heldenian Battlefield.
This could be cruel but it is essential to prevent 1 guild equal to1 town size
