Finally got around to trying the new BGs with the Guild. The map with the boat (like a big swamp) had three of us get knocked off the map. We were able to submit bug reports, check gear, send mail, etc as we were not in combat, but could not use "get me unstuck". Also, the stand still for a while feature (I guess it ports you into the action) did not proc at all.
The other team had also had at least one person knocked off the map, too.
