This is what it boils down to when you've run out of rational argument, light trolling. Yet you're an admin, showing everyone it's ok to wind up other players, other members of this community for lulz to lure them into a trap in which they can be incriminated, sure is a great example you're setting this community.
What arguement do I need to present?
Here is the thing:
This thread is a bunch of players discussing with a bunch of other players on the subject of the rules and how they are enforced. To be perfectly blunt, this will change nothing as non of you have anything to do with the rules. If this was presented to the people who are actually in charge of the rules then this might actually change something, but this is just some thread in General Discussion about a bunch of players saying "this rule makes sense, this one does not, this is ab00ze and this should never happen yadda yadda yadda." Okay... So?
Last I checked, this is not a democracy, so if you get a couple dozen players out of the 12K+ who play this game to say "this needs to be changed" then nothing will happen, just like the vast majority of the "game suggestion" threads in the suggestions forum.
If you want something official changed, go to the administration, as your peers don't have jack-diddly-shit to do with the rules so them agreeing or disagreeing with you is pretty much worthless.
EDIT:For clarity, if this was talking about some Game Admin Abuse then yes this thread might have merit, but the problem is that Nuffen did not act out of norm, he did what has been going on for months and months and months on what happens when two team mates are attacking each other. They both were punished.
The problem is that you want to change "standard operating procedure" and not "this Game Admin did something unusual." Nuffen did what other Game Admins have done countless times, and the rules do support his decisions. If you want to change the actual rules and procedures, expect a very steep uphill battle with Administration. After all, they like the current rules enough to have made them official, kinda says something.
