There is a huge issue and it needs to be addressed in whatever way it can be.
What I queue for, ranked or otherwise:
A fun game, randing between 20-40 minutes, where both teams try their best to strategize and win and offer sound friendly advice if needbe.
What I do NOT queue up for:
Shitty, toxic games, usually being unanimous surrenders at 15 minutes, where my teammates all troll, tilt, or scream 'it's just a fuckin' game bro just have fun with it BRO RELAX BRO ITS JUST A GAME' when they're feeding their asses off despite being politely asked to play safer, given gentle advice on how to die less, and even camping their lane for them to try and get them back into the game.
This "Oh it's not ranked so let's not try' mentality is as toxic if not more than 'flex queue isn't real ranked'. I don't care if you play Vayne top, I don't care if you play Orianna jungle. I DON'T CARE IF YOU PLAY FULL CRIT ADC ANNIE. AS LONG AS YOU ACTUALLY TRY TO WIN WITH WHAT YOU PLAY.
DO NOT UNDER ANY CIRCUMSTANCES EVER PUT SOMEONE DOWN BECAUSE THEY ASKED YOU NOT TO INTENTIONALLY FEED. DO NOT UNDER ANY CIRCUMSTANCES FLAME OR TROLL BECAUSE SOMEONE OFFERED BUILD ADVICE OR ASKED KINDLY TO STAY SAFER. DO NOT UNDER ANY CIRCUMSTANCES BE THE 'OH IT'S JUST A GAME' GUY.
