Since Bungie is determined not to allow matchmaking on all the truly rewarding stuff like heroic strikes and missions, I think it would be best if we the community form our own matchmaking process. I think we should determine a location within the tower where we can can gather if we want to do heroic strikes and missions, nightfall strikes, and even vault of glass. In these areas, we would know that others want to join up to accomplish these tasks and can easily join together and get going, rather than wait forever for friends to get online who may or may not join. Personally, I recommend the vanguard room, as it has a lot of empty space around the sides.
