I am completely against this. If someone can stay alive against a team in trials trying to kill them while also damaging theirselves they deserve to win the fight. And a request to make the perk only proc if a higher K/D is on the attacker than defender because you assume that player would win... That would only contribute to a system where players would (perhaps unintentionally) artificially inflate an already high K/D and significantly lower the chances of anyone with a low K/D ever increasing it. That, good sir, gets my 'silly request of the day' award.
