I'm guessing what you mean is something like this:
/setguildhome will set a home that all guild members can access.
/guildhome will teleport you to your guild's set home.
If you have no guild, you can't use this.
Pros: If your guild has multiple locations, this can be used to teleport (wait, teleport is underlined red?) you from your set /home to your guilds /home (Such as Abyssus to Sub Aurora)
Cons: This can technically be used as a second /home, you just make a guild with only you in it. One way to counteract this is to have it be required to have a minimum amount of members to set this (example 3).
Did I get this right?
