I just thought it was interesting If the very few games going on at one time meant they found a way to continue their premade ways.
ETA: sorry I hadn’t gotten fully caught up on that post and see that you already gave your similar thoughts @ comment 189. I agree it seems very odd that alliance pugs would pull of such short wins, unless the Horde meta has reverted to rush or they are coordinating groups still.
