As Kevan and me involuntarily showed, killing can be done without concernc for one’s own safety at the moment, as dying is not punished, only killing is rewarded. If we would loose a frag for dying, we would have to be more carefull even when killing someone. :-)
I am still thinking about a way to reward any shove that took place since the last time a Gladiator spend an AP. (Current example: my death resultet kind of directly from both Prince Andurils and Kevans shoving, but Anduril did not get a frag.
