I'm 14 and the only time I've made someone rage quit was because I was better than them. Also it is about maturity not age, I've met a lot of people that were immature and older than me and I've met a real mature person that was younger than me.
And since u mention it,yes,sometimes we go crazy with hackers we think all are hacking.Guys from,Punkbuster was it or another?I don't remember sry,said that they were spectating guys marked with others suspicions and they weren't cheating,they were just good players.
I think it's also common sense that in this world,over 6 billion ppl,not all playing ofc haha,but these millions of ppl playing,well some of them just have it in them u know?
I am jealous of them in the good sense,even if i never be as good as them.And anyways for me at least it's not about only how good u are but how much u care and can contibute to your team and also to the community.
