I don't mean people who are literally running into lane and offering up free kill after free kill. But if you are in a game and someone is 0/2/0 keep your mouth shut. I seriously don't know what people think they are accomplishing by going "GG x feeding, report them at 20 mins" other than hurting your own team.

It honestly just motivates people to do worse by instilling in "i need to prove to myself and get kills to show im not bad". Early deaths are easy to turn around

Even if you arent your teams support, support your team

Can I ***** at the duo botlane that are 0/8 and 0/7 between them at 14 minutes?

When it's ranked people including me naturally, tend to rage. But at the same time, everyone has a bad game once in a while, and they shouldn't be raged on very heavily.

I had a 7/5 Garen steal our blue.
I had a 0/6 support malph save me in teamfights, initiate perfectly, and lead our team while later help me backdoor the enemy nexus and win in the same game.
I honored one.
Guess which?

0/2/0 isnt even close to feeding.

0/7/0 on the other hand.

My advice: if you're going to rage, only rage after the game is completely lost. If you say something negative after a teammate dies, they will play worse, no ifs ands buts about it. It's entirely counterproductive to winning, so if you're going to indulge, do it after your winning chances are nil.
