Ranked has lost its meaning and is now a troll/4fun place
I remember a few years back season 2 up until season 4 players were very serious about ranked. People literally felt nervous every time they played a ranked game, I included. 3 bans per team meant only the most OP champions were banned and you always picked your best champion with 2 or 3 champions to flex.
You HAD to know all 5 positions well and also know at least 3 champions per role, no matter who got what you knew your team players knew how to play each role at least decently for their rank level. You always could count on your team playing their best champions and everyone tried their best to win, yes there was rage but everyone tried their best to win.
Nowadays people go to a ranked game like its a normal game, using champions for the first time or playing an ADC as jungle because they got filled and they don't know or own any other champions. Team comps without any front line or engage, 0 strategy is put into draft.
Also, the game is full of crybabies and/or man childs that can troll the game or completely ignore your lane just because you point out a mistake or tell somebody to play better.
And if there was a troll back in the day you could always carry the game when you had a decent lead over your lane oponent, nowadays you get punished for doing good, 1000 bounty on your head for playing good is a slap in the face to solo carry by Riot.
Now it only takes 1 bad/troll player to auto lose the game at 15 minutes, there is no late game comebacks anymore, Now with objectives like herald games are meant to be over when you have the slightest lead, all intended by Riot.
