I'd rather join a guild with just people I'm better friends with than a ton of random people so I'd love if guilds could lower the number of required people from 12 to 4 or even 6.
I have some people I'd love to join a guild with but not enough people to meet the member requirements. Considering a group can be a max of 4, it'd be great for guilds to be a minimum of 4 for those of us who would love to do guild stuff but not be forced to join with a lot of people they don't know well.
