Ata should add a feature where u can invite someone to a chat like clan chat only it's people u selected like party chat
If you really want to chat with someone in a group, just get them to join your clan... But I can see this being and effective add on later as a parle for clan leaders wanting to set up wars and such, just something else to assist the Devs In promoting the war system, because the easier it is for people to do something, the more likely they are to do it.
