For the last 2 days BGs have been unplayable for myself and several others while in a party. The queue to join pops up, it counts down players accepting, says forming group, then in the top right of the screen it says something along the lines of "someone in the party did not accept the queue, you are being removed from the queue". It then automatically puts you back into the queue, repeating the above process indefinitely. I sat through this for half an hour or so trying to get around it. The only way to actually get into a BG was to solo queue. In which the queue time was at most 3 mins.
Again, this was the case for several friends as well as myself. Grouping in a party worked fine on Morrowind's release day. 2 days after and beyond have been a headache. Just trying to spread some awareness, and hopefully find some way to get around the issue. Considering I've been waiting for some form of structured, small scale pvp since PC beta, it's highly disappointing that something so basic to MMOs, a group finder, continuously fails. And ultimately has had functional issues since the games initial launch.
