Learn to behave like a human being... or be banned... some people need to be banned for once!!!
Now my first issue is that this game has the absolute worse community in the world... and EUNE is the worst OF the worst... when someone tells you that your family should die, he shouldn't be allowed to play again... when they joke about cancer to your family and death to all that you love.... that is not humor... that is somewhere between psychosis and just an dark heart that respects nothing...
I used to play ranked but stopped because there is no point... all you get is constant flaming, no respect in the team and just little kids that rage and shout and cry about everything and always tell everyone how they are so good and the team is destroying their game... newsflash... if you can't get your ass out of your lane to help your team that is feeding or you don't even bother to ping a damn SS... yes, you're gonna lose...
Also, learn when to use the word report... I only use it to suggest that someone that is flaming at everyone should be reported for that... I never say that "report bot for feeding..." (I am usually in bot though... so bad example... XD). Anyway, when your teammate feeds, especially in a damn normal game, try to help him... give him advice, try to gank him, tell him it's ok and calm him down.. don't start shouting at him to delete the game like you're Adolf Hitler and that is your ruling...
I was playing a game a while back... there were these two kids that started flaming me and cursing at me in greek because my username is in english so they thought I didn't understand greek... they were saying my family should get cancer and everyone I love should die... funny story... at the time my mother HAD cancer (thankfully she escaped the danger)... their reaction... they laughed... and joked about her dying... and I am completely sure that these two kids are still playing without a ban... I am an adult and I can take some things without getting pissed... but at that moment when I heard them joking I was going crazy... I wanted to find who they are just to beat them up so bad that wouldn't be able to touch a keyboard again... but RIOT community doesn't seem to care... now don't tell me about summoner's code... BULLSHIT RIOT... people have been pissing on summoner's code for years now...
Lastly... I am, or I was before I stopped ranked, a Silver player... but I have IQ... so when I play against someone that is OBVIOUSLY much better than me, I don't start flaming him and crying about how his champ is OP and he has no skill... ok... there are OP things in this game... but an outplay is an outplay... be respectful to everyone... teammates and opponents... being an asshole doesn't make you seem cool... it makes you seem like someone that NO ONE would ever want for a friend except for the people that have the same low IQ and no manners like you... Saying EZ every time you kill someone is not cool.. it's just senseless bragging.. because after that you will play with a seriously good player and he will kick your sorry butt... and I say all that because I KNOW EXACTLY how it is... because I may be mediocre at best at LoL, but I am Division 1 at another game... FIFA... and so I know how it feels to be low and high... been on both ends...
I was actually playing with a kid from Austria a while back... I was in Division 6 in FIFA because you have to start from the bottom every year... anyway... I beat him 11-0... the kid sent me a message because he wanted to play again with me... so I made him a friend and we played a few unranked matches... each time I explained strategy to him and how to move the ball he played better... he didn't beat me of course... but you do understand how huge it is to go from 11-0 with 0 chances to a 4-1 where you are actually playing too in a couple of days... it's HUGE... and he did that because he wasn't a sore loser...
So, be respectful, play the game like a game... your life doesn't depend on it... watch WHAT you are saying because some things are simply UNACCEPTABLE... respect your teammates and opponents (try to help worse players and learn from the better ones)... and RIOT... BAN SOME PEOPLE... some need to just be banned...
Sorry for the long post, hope you read it all and not be bored :)
