Greetings,
Thank you for the feedback in regards to instanced zones in the Stormblood areas.
We understand that these field instances can make it difficult to group up when running open world content or gathering as a party, and we apologize for any inconvenience it may have caused.
Due to the specifics of the programming, many of these requested features such as being able to choose which instance to teleport to or having the system prioritize whatever instance your party members are currently in would be very difficult to implement.
While we are aware that this is not ideal, we ask for your patience and understanding as these field instances are tentative measures intended for congestion relief and load reduction as we try to make the game as smooth as possible for all players.
