If you were slain for a word vs word situation that leads to nowhere , report this staff member. We need to know stuff like this.
If both those players had actually fired at other players (staff had checked logs), and the staff member saw you doing it then the slay is justified. If on the other hand, they slayed you by simply spectating and saw what they thought was an unjustified kill then the staff member is in the wrong.
My mistake. You are right lol, my wording is not the best. What I was getting at is if the staff had checked the dmg logs, they may have found one of the kills to be justified. If you killed another player in turn because they killed someone, it is not RDM and you should not have been slain. If you THOUGHT they had killed someone (but they didn't) and the logs support that, then it is RDM. The issue is we are making a lot of assumptions without any input from the staff involved.
No problem. If at anytime you feel a staff member is not doing they're job, or you want clarification please do report. I believe this answered your original question, so thread will be set to answered.
Even if they are invalid, that does not mean you shouldn't report them if you feel you have been wronged by a staff member.
