I want to add another thing: (maybe that even exists longer but I noticed it several time during the last days although I wasn't that often in WvW for obvious reasons):
The map-selection says that a map has a queue (e.g. Q=2 ; usual in the range of 1..3)
At the same time on the map itself: outnumbered! From my personal impression: the outnumbered sign is right, the shown queue is wrong.
Unfortunately that leads to this issue:
You call on team-chat that help is needed to defend garni (or SM) and the answer is (understandable): you have queue, you have to deal with it. Those few who try anyway just come through without waiting.
I saw this quite often in the last days because we have some issues with inbalances in the beta-matchup.
