We have multiple things on Vigor that are not that good to play with friends or against other outlanders.

Things that hinder our ability to play as a team:

• Can't drop items on the ground.
• Can't share ammo with teammates.
• Kill cam will show us as spectators instead of looking through their camera when you die.

Things that would be nice to interact with people:

• Starting game chat or Voice Lobby
• Voice chat by proximity
• Chat for PC players

All these could be implemented with little to no effort and I believe it would greatly improve the game experience with friends.
Not only that, it might allow players to interact with each other and let them decide if they want to fight or if they want to just talk their way out.
