Can't Ranked

"If you start tilting while playing ranked then you should take a break"

This basically means that I will be doing 1 ranked game per day because all I get in Platinum are team mates born to make me tilt. At this point I don't care about winning/loosing. All I want is to have fun in a competitive match where I can test my skills. If i go into a blind/draft normal game, I get paired with gold 5-gold 1 and end up shitting on them without improving. If I go into a ranked game, I get junglers farming my lane, then proceeding to kill themselves to the ennemy laner. I dont mind it until it starts being the 3rd consecutive death in a row in different lanes. I dont mind toxic players until they start spamming pings on me because i didnt go in with 1/5 of my hp and all my cds down. I dont mind feeders until they actually start inting because "they are not worth anything" as if summoners/CC they could provide meant nothing. I dont mind loosing LP until i get 3 unwinnable games in a row. TL;DR: I dont mind having difficult games and some challenge once in a while but enough is enough (hope this means the same thing as in french). Toxic players never get banned and I've never heard of some casual player getting a day ban for inting. If somone is having a bad day then a 1 day ban should be enough to let them rest and be in a better mood the next day. Next season is coming soon and I hope I'll be able to get diamond without having to play 1 game a day because of tilting.

Good luck in solo Q and please comment below suggestions on ways Riot could reduce the community's toxicity and help players not tilt.
