Ok, now this is very, very frustrating. First, it seems that you cannot help teamates who are fighting. While I do like this a bit for duels in the arena, it means that if you are in MMD with a teammate and they get ganked, you cannot attack them.
Also, and a real pain in the ass, If you try to fight someone in MMD and Q them, they can deprive or cast any nano on you easy, and all you can do is fire back until they Q you, it sounds strange but its happened since last patch.
Anyone else notice this? Getting the cannot initiate pvp message while still under attack?
