After waiting in the queue for a while I finally entered the new Silvershard Mine Battleground. The Alliance was already losing at this point so I didn't really get a chance to figure things out from the start and everything was very hectic.
I gathered that it has to do with the carts that spawn and moving them by standing in the circle around the cart, but what actually makes the cart move? How do you score points? I guess I am looking for a breakdown of the ins and outs of Silvershard Mine as there appears to be a lot more involved than a simple capture the flag.
