We have all been there - hearing the call from one of your fireteam members: "I'm out of heavy" - "Do you have any synth?" - "No" And yet you have some sitting right in your inventory - useless to your buddy who's under fire. In my opinion, adding the ability to give one of your fireteam members one of your ammo synth packages would create a very nice interactive quality. Obviously, this would need to only be available in PvE. Edit 1 : Looks like the response is fairly overwhelming for the small sample size - Gaurdians! Get in here and cast your vote!
