Rank games are horrible this season so far

Im going to be honest here and not trying to be toxic but everyone on my team is just trash. Now i can say i was plat 4 before i left off and now the provisonals have got me going. I am 1-5 currently and i have been doing amazing the whole game until the other fed laners come in and kill me. This might sound like an excuse but its every game. The game i won was barely even close and i feel like i dropped to bronze every time i play these games. With the dynamic queue being added im getting messed up from these 4 man premades who are having communication when my team barley types anything the whole game besides being toxic. As a result, it is a loss, however the dynamic queue was shut down and played 3 more games and lost them all. The whole time my team mates are arguing about which is the right and wrong play and ima be honest both of them were retarded. Riot needs a way to ave team mates that actually care about the game instead of going ad leblanc support and losing off that base reason. If i somehow get into low gold because of this reason im going to be insanely mad because why am i getting punished for my team mates mistakes? This is just annoying and riot shouldn't penalize for doing good but your team mates doing bad. Please send this message or understand what is going on. If this continues league will be diminished in no time.
