Played wonderfully during the closed beta before christmas but last night I kept getting kicked and a message saying the party has changed and it is returning me to main menu?
And talking to my party and they are still ingame and playing…
The major disapointment is that my rank went from Gold III down to Gold II and almost Gold I due to disconects? 
This is happenning to me as well, i cant get into a game in with a party and consistently have this problem.
