The security penalties for suicide ganking will be more severe and the Concord response will be faster. Two frig will come in instantly (lag allowing) and a battleship will arrive to blow the offender to pieces. Also no more insurance payout when Concorde is on the killmail !
Not unreasonable changes. Suicide ganking used to be a pretty rare thing, but lately, for example on the Amarr -> Sivala route, you come across several camps of suiciders, it’s getting a bit out of hand. Luckily I have never been a victim of this particular tactic. Only drawback will ofcourse be the accidental shooting someone that occurs on rare occasions (cough cough).
