Let me leave games please.
This game needs to allow you to leave ranked games and maybe take like double the LP loss for it or something. Half the reason people get so frustrated in this game is when your playing a game and someone starts to troll or intentionally feed you cant even leave the game. Your stuck now in a 40 minute long game with someone basically wasting your time and taking a dump on your competitive spirit over and over. You can't even say anything to them or you might get in trouble for it. You literally just have to sit there and take it over and over for 40min. After multiple games like this it's no wonder people snap and finially flip out on some poor soul who makes a small mistake. Their venting built up frustration from previous games.
Think of it like this. Say your out walking down the street. And some random person just walks up to you and grabs your phone out of your hand and throws it into the road, watches it get run over by a car and smashed then laughs in your face. If this happened in riots world you cant say or do anything to this person. But in the real world we all know you would punch that person in the face.
League of Legends is a so called "E-Sport". Well, in Pro Basketball, Pro Football, Pro Baseball. Competitive players talk trash to each other all the time. Could you imagine if they got kicked out of the league for it. It would be considered the biggest joke of all time.
How can you combine the world "Competitive" and "Carebear" in the same sentence? You can't. Its just complete foolishness to even try. You can try all you want but in the long run nothing will change. Any time you have any kind of competitive Game/Sport/Scene. Anytime there is competitive drive in 2 or more individuals. They will clash. Its just how it is. You can throw any arguement you want at it, but you all know its true. Trying to eliminate it is a fools errand.
Now knowing this and trapping people in that with no means of escape or leaving when someone is deliberatly trying to ruin your experience and forcing you no means of dealing with it is what is destroying this community. You can claim the report button is there for this exact reason but we all know the report button is useless on actions, and only good for words.
And I can already tell some people will be like Well I only play for fun not to win, and my response to that is that is EXACTLY why riot has made several game modes including Normal games and ARAM, etc. Ranked games are for people who like to play with some competitive spirit. For people to want to try to win and see how good they are compared to others. For people who want to try and get better and improve.
Maybe put a disclaimer or warning when people queue up for ranked, such as "This is not a normal game, people in this mode are more competitive in nature. If you can't handle a competitive scene then do not queue up for this game. Pretend its gym class and go sit on the bleachers."
Just my 2 cents.
[Edit]
I forgot to add another thing that annoys me. When your down 3 kills and 1 turret at 12 minutes and for some reason your team wants to FF pre 15 and you hit no. So they call you a troll and decide to run it down mid and intentionally feed and you report them and nothing happens. It's not like this doesn't happen often either.
I've been down 10k gold, 15k gold, 20k gold, I've been down 4 players to 5 many times. And many of those games turned into victories, simply because 1 of their players got caught out and picked. Its freaking SOLO Q. Its not League of Legends Super Pro League Challenger Level TSM Squad your playing against. People make mistakes and throw games constantly.
Because I refuse to throw away 25 LP and some MMR rating in a 12 minute game that is not a definite loss yet its okay for them to intentionally feed and give me a free loss? The report button is a serious joke.
