This game is killing me because of all the nonsense and bullying

I was playing LoL for several years now and the game starts to kill me slowly. In 50% of the matches i get at least one of those people/behaviours:

• Flamers flaming me cause i play offmeta support like Fiddlesticks... accusing me of "Fiddlesticks is not a support" These people have 300+ wins and can not even read champ description because Riot even states fFiddle is a support.
• An ADC who is either having 2000ping, does not watch map, or sleeps
• Premades ganging up verbally on you cause you are just the support
• No pings because of premades think they can just use voicechat
• Getting preselected champs banned in champ select with the excuse "I did not see it" (How does such a player even play when he can not see 5 icons? - - Getting preselected champs banned in champ select with the excuse "Play a proper support" when preselecting Bard/Fiddle/Maokai/Brand
• Get insulted because you took 5 cs while the ADC was not on lane and the minions would have died before he arrived lane.
• Getting insulted because you don't want to 3vs5
• Getting insulted because you don't steal Baron alone as Thresh (basically 1vs5 and steal)

I am annoyed that i can not macro any responses because it is always the same in every match i have to type the same shit over and over again. I don't want to play with such guys it sucks. Please make something like a "drivers license for LoL". I don't want to deal with those people any longer.

By all means i am not the best player but i don't want to play with people who have no common sense.

Since i can not tell all the people in game what i feel in that certain situation cause it's against the summoners code, and it is super frustrating for me to play i had to tell here. FeelsBadMan
