"It's flex, who cares teehee xd"
I'm not seeing your point here, it's a ranked queue which means you get rewards for being gold up. Just because my preference is flex queue doesn't mean you have to play while intoxicated with your trio queue, laughing your asses off in discord and fucking trolling the entire fucking game. That isn't fair for me, nor the other random on your team.
Seriously, for anyone who has this attitude, re-evaluate your life. It's insanely fucking selfish and inherently childish, you're wasting everyone's fucking time because you're having a blast inting your face off.
