Ok, so I went ahead and looked at your match history and I think we might need to consider that you are the problem here. Not your team. Not the league community.
Out of your last 32+ (I stopped counting there...) ranked games you have only played Pantheon. It's ok to main champs but something like this simply doesn't happen unless you blatantly disregard the rest of your team.
I also looked at some of your most recent games, played today. I can see the double mid champs. Interestingly, in many of these games you are not picking before the other mid champ. In other words, by the time you lock in Pantheon and decide to go mid there is already another mid-laner locked in.
Why do you not, at this point, pick another champ and go to another lane? This is a team game. You are not guaranteed your lane and champ of choice every game.
Coming on here and acting like a martyr because you don't get your way when you are clearly not trying to be a team player is disrespectful and dishonest. And frankly, a waste of our time.
