AFAIK, when somebody gets killed by ack, kill goes to the nearest enemy. IMHO this would not be the case. If somebody gets killed that way, kill should go to Ack operators, or to nobody, but never to an ack hiding guy.
I realise this is a valid defensive tactic (since I love field defense, I use it extensively), but I think It's not fair to award guys like me with more kills than the hard earned, usually worked on gun ability and combat manouvering (either BFM or ACM).
