I'd like to hear of experiences from people around the world about their experiences with the shield.
I live in Australia and I for the longest time I didn't know there was a latency meter in the game, because mine was a red box. Obviously I have horrible latency for this game, thus trying to block attacks for me is the opposite of what I should be doing. I can not block an attack in progress, I can't move away from an attack in progress. If a zombie is any where in their attack animation, its going to hit me.
