In Alterac Valley, we have forty players and four capturable towers or bunkers. Sure, the opposing faction can defend the towers/bunkers allowing it to be recaptured, but the whole business of racing to capture one -- again, personally -- turns every Alterac Valley into a race. This means lesser chances of defended towers. Realistically, if players tagged and defended until the objective burned down, only 10% of the team would be able to accomplish the Achievement requirement in every match. I'm sorry to tell all those who are allergic to PvP that you'll actually have to play quite a number of Alterac Valley matches just to get this one. Unfortunately for me, on my Battlegroup, playing Horde-side AV is like pulling teeth.
