This is NOT ghosting.
This is just using communication(which seems to be missing a lot these days),and has been around since the start of internet MP games.
The admins are totally right,this is a TEAM game,the team with the best comms,wins.
Agree completely
I however feel that the killcam in BF4 is totally wrong and compared to insurgency's killcam it only shows the enemy player (When killcam enabled) just shows a 1 second directional shot of the face of the enemy player.
True ghosting is spectating an enemy player and giving a constant update to his/hers location!! I think reporting an enemy players position after being killed and giving a call out "1 enemy at example flag A" is just good team work and communication!!
