Did not work for me, all i did on my 49 shaman was stand by the zerk hut in queue for a 2v2 skirmish, and when there was about 15 seconds left on the queue, i grabbed the zerk and entered. I came into the game with no zerk, and i noticed that when i grabbed the zerk is a beneficial spell, not a debuff. I know zerk use to be a debuff, but they must have changed it to a beneficial buff, so i doubt it works anymore.
