I'm assuming you were attempting to reply to me. Rather, you replied as a new separate post, but that's okay. I'm active and I read your wall of text.
Let me just say this to you.
I have a friend, who is mechanically twice as good as I am. He can carry most every game with any champ. I am dumbfounded at how good he is at playing games (not just league, he was a semi-pro fps player as well).
I shot straight from Silver to Plat 5 in 100 games of playing ranked.
He couldn't get past mid-Gold last season, and now he is stuck in Bronze.
Why is that? He's a better player than I am. He's a better teamfighter, better 1v1'er, he has better knowledge of the game, a bigger champion pool... but he always blames his team and gets angry at his teammates.
I am the very testimony for players who do not deserve their ranking, but get there through sheer teamwork. I probably have more fun playing the game than he does, and I make more friends on League than he does. I have more comebacks than he does, for sure.
Don't blame your teammates for anything. As confusing as it may sound, they are not there for you. They are there for themselves. Just like you are playing for yourself, they too, are self-centered creatures called humans.
So don't complain. Show your worth as a player by being encouraging. Be a leader with charisma, and again, never blame your team for anything. Your teammates at bot gave a double kill to the other team and you lost the game? Your fault. You should have gotten three kills at top, and two towers, and roamed mid and gave two kills to mid. See what I'm getting at?
Good luck.
