Just an idea for those who are having trouble reforming.
The biggest problem with most people is that they like to communicate, chat it up, and it is understandable. You know what I am talking about, that guy who has typed a whole story of randomness, from his last game, to his build, his favorite quints, etc, before 4 minutes.
The biggest thing as well, is most people have the "COD" mentality, and that is that when something happens that they did not plan, within an attempted plan, so lets say you try to make a bot play as jg, but adc n support literally wait for you to chase them halfway back to their turret before attempting to engage, and flash to try to overextend, and it makes you mad, you were ready, you have everything planned, hell, you even pinged several times.
This moment, right after you die because you engaged first and they didn't engage properly, and then they flash in to overextend and die as well, this is the moment that I am going to be talking about.
I don't know how to describe this feeling, but you want to smash your keyboard, you really do.
At this second in time, when you come across this feeling, do not type anything into the chat log for the rest of the match.
The second negativity starts flying around, shit just gets worse, hits the fan, and flies all over everybody. (too much typing, not playing, getting killed not paying attention) Even if you are talking in chat, ANYTHING, it will only get progressively worse here.
The biggest thing I find is that people who are able to do this, the second they realize that super negative rage feeling, and calm down, and realize nothing else is going into the chat log, it really helps you realize it's just a game, bad plays AND games happen, and you will try next time, unless the scenario I just stated previously occurred, if they got fed, then help other lanes, let them sadly wallow in the shit they created. Telling them so pointlessly instigates further verbal abuse between eachother.
Focusing on this has helped me huge, HUUUUUUGE. The second I have that ragey feeling, I know I have to chill out, calm down, and just play.
I honestly hope this helps some people, as I see alot of people stating they are apparently attempting to reform.
