If someone gets tked and complains then its admin time. if someone is breaking a rule and someone complains then its admin time...
This is personally the way that I deal with it unless it's low pop and potentially damaging to the server. Of course, there are numerous situations, and that's where your judgment comes in.
Sometimes people don't complain and just leave.
However, if you break a server rule and an admin slaps you for it, well... you can't really argue.
That's not coming from a dystopian power-starved video game admin- it's a rule.
I can't speak for Murder's situation, but from what I understood there was a TK before the round actually
literally ended.
The end-of-round rule is in place because not helping your team at any time is potentially detrimental to your teammates, even if it's 18v2.
Yes, the team with 18 will most likely win, even if you managed to TK half your team down to 9, but gaining a multi isn't the only important aspect here;
It's also about generally helping your teammates, whether that be in making life easier for them and killing the last two quicker, or protecting their KDR by lending a hand.
Just my thoughts.
