A simple fix to a lot of the phasing problems is to allow group leader to have phase priority for group member thus allowing people to be able to play with friends and participate in previously completed content as long as their group leader hasn't. There doesn't even needed to be any special new mechanism created as "travel to player" is already in game and would facilitate zoning to group leaders phase.
