1. The option for subgroups. This isn't too important, but say you make an RP that has multiple packs/prides/whatever. It would be nice if each pack/pride/whatever could have it's own group, but still stay in touch with the other prides/packs/whatever.
2. The option for a second-in-command. Say you're away on vacation, but you still want to get members in your RP. You select the most reasonable person in a group and they can add members whenever they wish. However, they cannot rename, kick, or delete the group and it's members.
Yeah, I know not that good o3o
