What you should ask on the survey is why players are toxic, I will tell you what has filled a lot of my losses lately, and caused players to be toxic sometimes starting right there in champion select.
. Too many players auto locking ADC, or Support champions.
. Too many players refusing to communicate in champion select.
. Too many players just instantly banning champions in champion select no communication.
When something goes wrong due to other players failure to communicate, they get toxic at the only person who did communicate, and start raging about nothing but Pick Order all game long, then go in the game usually doing very bad themselves, threatening reports, and spamming hateful things in chat.
Riot needs to enforce communication in champion select, because every game I play when I am unlucky to run into Toxic players I just report (Verbal Abuse) which includes asking others to report others, or (Refusing to Communicate) if they do not verbal abuse, sometimes a player is unlucky to run into many games where players are like this a lot.
And after you dodge your first game and wait 5 minutes losing 3 LP you have to wait 30 minutes + lose more LP on another dodge in the same day even if players are toxic in champion select so how can you avoid players like this its almost impossible.
But I did fill out the survey on it although it was more of trick questions because there is no accurate answers because it honestly depends on the type of players you get matched with.
