seems like iv had the exact opposite problem, game worked fine till ROI launched and since then getting on the same fireteam with my BF has been a nightmare. The other evening he had to drop out of a raid i'd planned because it literally wouldnt let us both on the team.. without disconnecting or rebooting, if he left the team, I was immediately able to join it (and no it wasnt full - and because of this we were left scrambling for a 6th team member!) Its total crap and they need to sort it out.
