I probably should have put this in my other post, but nothing I say is an official response in any way. It's just my opinion, I have nothing to do with, nor any knowledge of this situation, or how the NA admins operate in general.
That said, you completely missed this part of my post: "Admins are trusted enough to use their own judgement in situations like this, but not every admin is going to have the same opinion." The common sense rule is exactly what I'm talking about there.
Bypassing the autobalance is something entirely different, it was implemented to stop people trying to endlessly joining one team, then the spectators and back again till they got the team they wanted.
Leeching only applies when the person is not contributing to the team for a longer time and usually repeatedly. Chatting, being afk for a couple of seconds, running away from somebody you know you can't beat, all of those could be interpreted as not contributing and none of them should result in a ban. Muuki's post is his opinion, my opinion is that "bro-coding" really isn't an issue.
The rules are honestly just there as rough guidelines and most of them can be interpreted in 50 different ways, the admins in question are the ones that interpret the rules and decide which action (if any) needs to be taken.
Your entire problem is that you think these guys hurt your teams win chance. I dread the day a rule that forbids that gets implemented. That day will be the death of fun in crpg.
You also seems to expect a lot of profesionalism from a bunch of unpaid admins in a mod.
