When adding yourself to a queue to join a map, if you have the WvW window open showing the list of maps, if your queue pops during you are viewing this window, it automatically resets your queue instead of popping that Map Ready Travel popup. So you are thrown to the back of the queue.
You dont get teh TRavel popup and the sound associated with that doesnt play either.
You are automatically entered at the back of the queue again.
Complained about WvW before it became cool.
I used to be a PvE player like you, then I played Guild Wars 2
