i came online to play 1 game with a friend im experiencing alot of lag in game and also my friend invited me to part i was not able to accept the party invite but game went through anyway i clossed the game was not able to rejoin.
just wanted to report it as a known issue
Edit 14 july - i just wanted to update this instead of making a new ticket i had 1 bg Duo game and had no issues but then i had another game where we and my partnet very friendly guy btw 
we were first lookin strong and unfortunatly i got disconnected and was unable to rejoin .
I had to log out of battlenet and back in and now i seem to be fine again,.
I rarely get dcs but just wanted to report this too this one of my fave modes
