Around the 20 minute mark I believe, what the dev is doing is standing in the middle of the group so they can't start fighting. It wouldn't be fair, and he would be counted as an extra AoE target fucking things up. The dev is probably mad because everyone is pissed in WvW right now over bloodlust or match making so they're not playing WvW but guild fighting instead until ANets retarded ass actually does something to fix things.
Let's be honest, ANet doesn't fix things.
