I would agree with you if I didn't see people rage so much in game.
Half the time I'll see someone instalock and then demand that the others pick something to accommodate them. Then there's the people that spend half the game raging at their team over something trivial at the start of the game, or trolling and/or going afk. Foisting blame instead of just stepping up their own game. They can really make this game frustrating.
Some people take normals too friggin serious.
I don't play ranked, but I can't imagine it would be much better unless playing with friends. The only difference is they ban champions that I probably want to play.
Haha its opposite for me although i insta-lock people complain to me, even though i insta lock jarvin or someone strong lol
