How to win every game in ranked, true fact
Dodge.
So far every game I have lost on this account (only two), have been because when I tried to dodge, the game didn't register it and loaded the game anyways. I knew the game was going to be a loss before it started, and sure enough we lost those 2 games. However, every other game has been an absolute stomp.
How to dodge?
Remember these things for each role.
First of all Op.gg all the names in your lobby of course, and check your team.
TOP LANE If your top laner has less than 35% wr on their selected champion, or average 7+ deaths on the selected champion, DODGE.
JUNGLER If your jungler has less than 50% wr on their jungling champion, dodge. If your jungler is autofilled or first timing their champion in jungle, dodge. If your jungler average 7+ deaths on their champion, dodge.
MID If your mid laner has less that 40% wr on their champion, dodge. If your mid laner is first timing a hard skill champ like Yasuo, dodge. If your mid laner average more than 7 deaths on their champ, dodge.
ADC If your ADC is autofilled, dodge. If your ADC average more than 6 deaths on their champion, dodge. If your ADC has less than 2 overall KDA on their champion, dodge. If your ADC has less than 50% wr on their selected champion, dodge.
Support If your Support averages more than 8 deaths on their champion, dodge. If your support is first timing a support/autofilled support, dodge.
Do all this, and you will win 100% of your games I guarantee it. The only exception would be if the enemy team had an equally balanced team or smurfs. This is what determines the stomp or be stomped meta is these steps. For me personally, I normally just look at ADC/Junglers role and make sure they follow my guidelines, however if the support/mid average more than 7 deaths I will dodge 100% of the time, because all that does is make the enemy more fed and makes it the snowball RNG meta.
