Okay so I am curious. What will the purpose of a guild you start or want to join be? I mean will it be a pvp based guild, will it be based around crafting and gathering items? Will it be there just to help people level, will it be a role playing guild? etc etc.
Me personally I enjoy guilds that help new players and everyone else. I love to be part of guilds who will be willing to offer advice to new players, make new players feel welcome, and help each others and others on quest. I love being a part of something worthwhile to the community.
