This is one of the best things i have ever heard! If bungie does do it, however, they should also update there mobile app to automatically place your character in a chat feed that includes all other players in the event. Coordinating and assault with hand gestures would be frustrating and time consuming. A small map should be available were people submit war plans on the map and then they are votes on. The person who's war plan is chosen is then picked as the defacto commander for the event, helping to coordinate the offensive and marking enemy positions, until or unless he is voted out and the next person is chosen to lead for a time. This map should also show player types and weapons, so, for example, the snipers could be brought together and sent to a roof top to help support the vanguard by taking out opposing enemy snipers or just enemies that are to weak to do much harm, but are still slowing the main offensive down. The key to this battle would be communication, so an audio function on the app(they should also put this on pc, not everyone has a smart phone). Also, there was a piece of concept art from a while back that showed an AI in the city with a sniper rifle. This leads me to believe, that if not enough guardians show up, or were getting our arses kicked spectacularly, the number of "police" AI can increase, or some other subtle event can occur to bring the attack back into control. Thats just my two cents; what do you think?
