Through all the whining and criticism about Destiny (Which is quite exciting in my opinion) here is a constructive proposition for the community. Since you probably noticed, there is no chat system in game. This means it is quite hard to find other Guardian for end game activities such as Nightfall and Raids. A solution to that would be to designate places in the tower where people seeking for a certain activities could meet. For example: You want to do Vault of Glass but you don't have any friends... , or any friends that reached level 26 yet! But you know that, in the community, people wanting to take the Vault of Glass Raid go on top of the PostMaster building. With that said, you could go up there and randomly add the others standing there to your Fireteam (because you know they also want to do Vault of glass), maybe exchange some message and you would be Raiding in no time! I've created a map with possible location, feel free to share it with your friends so the community can use this to compensate the lack of a proper in game chat system!
