One thing that would be nice is if the game would let me start a leve by myself if I have party members in other zones, rather than telling me that they're "too far away" and not letting me start the leve. If they're not in the same zone as me, I'm probably not trying to do the leve with them after all.

Sometimes I'm not in a party to do stuff with people, just to have an easily accessible conversation channel with friends without having to leave my LS chat.
