While I played the beta I focused on killing enemies i rarely got much ingrams during mission or the strike. This was until I received a bounty that required 50 or so head shots. Once I started focusing on headshots, I started to find more ingrams (granted I could have been over looking some, but there was a noticeable difference). Did anyone else find this to be true? If this is the case it is a good reward for those who do headshots.
