Remember that 2018 ranked message we all got?
"Due to the top of the ranked ladder shifting down, the vast majority of everyone will start off lower than their previous rank." Or something like that?
You know who the minority of people who haven't went down are? Every single person who plays Ranked for the first time.
They're still getting placed in Silver for their first time, and they're still making silver games really tedious and painful to endure. I used to be G2 before the preseason came out of nowhere and started fuckin' with my mmr. Then when I win 8 of my placements and get sent to S3! I think to myself, "Oh, I can get out of silver a second time!" And I probably eventually will! But holy SHIT. You have no idea how many games will have me dealing with an ADC who auto attacks minions in every single teamfight and says "Lol I'm using the attack-move function! Report this guy for toxicity, everyone!" Or someone equally as bad. When League turns into a team game, weak ass garbage like that will always tip the odds in one team's favor. This wouldn't be so bad if that didn't mean I personally had to deal with a whole team that has more items than me, as well! That's un-carryable! People can't carry that! Skill doesn't mean anything if the enemy team knows they can ignore your feeding ADC, Mid and Support just to cc-lock you as a tank for a good 10 seconds! Because in that time of you getting focused for 10 seconds, your ADC, mid, jungler and support will all simply refuse to do damage, and you'll end up just staight-up dying for nothing! And then once the late game shows up, that 7/1/10 score you worked your ass off for will turn into 7/2/10, and then 7/3/10, and then 7/10/10! Because no matter what you do, the odds are entirely against you!
So, why can't new players get sent straight to bronze for their placement matches without changing where their amount of wins takes them? Wouldn't you rather a good player carry in bronze for 10 games before getting sent to gold? That can't possibly be worse than an idiot absolutely RUINING 10 silver games and degrading the lives of 40 other people in the process before getting sent to bronze.
