Toxicity attitude
I think that there are plenty of nice and good players, however the issue is that when these players see something, they don't do anything.
I don't understand the thinking. We've all been flamed by ragers... I was recently flamed by a man who is arguably an idiot, who fed lane so hard to a Leblanc his lane became dangerous, and literally blamed me for losing the game.
But because people flame hard, I do my best to resolve issues when people start pissing off (Just remember guys... it's... a game....), exactly because I've been flamed by ragers. It's your responsibility to say something and do something. This doesn't mean you start flaming the rager all the same or anything, but you should be helping your teammates. This also goes into gameplay. If your teammates, who were doing fine start tilting because someone is a complete idiot, then you're more likely to lose the game- We KNOW this is true. When you see someone getting flamed and of course, someone flaming, we generally just hold it at arm's length and go "good thing it's not me" But that's the dumb thing to do. Either the guy getting flamed is going to tilt, or he'll start fighting back... which are both understandable things to do.
We don't think about it... but flamers help you lose games. We should just automatically be helping support people who are getting raged at, but if you want more encouragement... keep in mind what these flamers really do.
