The new achievement system has meant that everyone and their mother has started taking part in WoW’s World Events. The reason is probably the lovely Violet Proto-Drake you get as a reward for completing all the individual tasks.
However, I wonder how many players have spotted that part of the Brewfest event meta achievement requires that players have Brew of the Year. This sub-achievement requires players to sample a different brew each month that you can only drink if you are in the Brew of the Month club, which I believe you can only join in August. If you joined last year and have been drinking the brews each month you have nothing to worry about, but if not it’s going to be September 2010 before you get your drake.
Unless Blizzard removes this as being one of the requirements for this achievement of course, which they are not willing to do at the moment.
