As has been discussed in this thread (Premades have completely ruined the PvP BG experience. Do something already), there is no blue response I am aware of that aggrees with your statement. The line you quoted does not mean premade sync queuing raids is allowed. It is open to interpretation.
I am aware. That wasn’t the point. The point was that it was eventually addressed and explicit rules were established. The same cannot be said for the topic at hand.
