I agree with you that only INTENTIONAL feeding is a bannable offense. It even says so in the tribunal guidelines:
4. Punish bad behavior, Not poor playing
Being bad at the game isn't a punishable offense. You should be looking at more than the score or item build to determine a verdict. A player purchasing flagrantly bad items is another thing entirely. Use your judgment to discern between bad players and trolling.
Also, from the summoner's code:
Leave No Newbie Behind!
ďBe an opener of doors for such as come after thee.Ē -Ralph Waldo Emerson
We all started somewhere, and if weíre going to do justice to the people who helped us move up the ladder, we have to start by paying homage to our roots. If you see a player having a bad game, or who clearly doesnít grasp the fundamentals of the genre, try offering some constructive advice. If you do so in a civil and friendly manner, itís likely that they will be receptive. Oftentimes theyíll be downright grateful that somebody took the time to let them know how to improve instead of yelling at them.
Never get frustrated by an inexperienced playerís performance. At some point, you were just as green as they were, even if it was the day that you downloaded the League of Legends client. Have a little patience, and try and help the player step up to a level where both of you can enjoy the game. At the same time, donít be discouraged if they arenít receptive. Some small percentage of players will get hung up on the notion that they donít need anybodyís help, and, no matter how politely you try to lend a hand, they wonít want to hear it. Thatís no reason to give up on the rest of them!
A lot of people fail to realize that and think that feeding, regardless of intentional or not, is reportable and bannable, which is completely false.
And this really frustrates me. Just the other day I was testing Kha'zix in a BEGGINER bot match and a newbie was trying Kassadin. The Ashe and Teemo were raging at the Kassadin for being a newbie. The guy was level 7, just ogt into the game, and was already raged at. The Ashe even asked us to report him for feeding, which is ridiculous.
Anyway, for some reason your tribunal case isn't working for me (endless loading). And since I can't see your reform card, I can talk about your behavior or try to check if you were trolling or not. But if you're sure they got your case wrong, send Riot a ticket and they'll sort it out.
