I have been trying to queue for battlegrounds for almost an hour, I tried re-logging, travelling to another location, and even tried on another character, but it just won't work, it kept saying that somebody declined, and for a while wouldn't even let me leave the queue, with the ready check popping up every 5 seconds and then cancelling. I then asked others, who are apparently having the same issue with dungeon group finder. I'm not sure if this problem is only on EU, but am about to log on to NA in the hopes that it is working over there...
