For all thouse who think games can be carried so that you win every single one.
Was gona make a long text but here is a short version: Lanes with most impact in order: Jungle Top Mid Support Adc
Games can not be solo carried. The BEST thing you can do, is to out scale the enemy laner by getting perfect cs and in the same time shutting down the enemy laner by denying him Cs and Exp. By doing this you get an Item and Exp advantage over the enemy laner. (we can call this bonus points). You use these bonus points to help other lanes, meaning if Ur ahead you can roam, but Ur loosing Ur lead in lane because you roam.
So the end result is: If you are lucky enough (yes the mm god's are real) to get decent teammates so that at least 1 more lane is wining or both are loosing (but not by far), yes you can carry it, by aiding them enough so they can claw back into the game, and still have you snowballing.
And if you are unlucky you will get 2 lanes that completely loose their pressure to the point that even if you spend 24/7 helping them they cant go back into the game which will ultimately make you fall behind yourself and loose the game.
Point of the story: There are some games that are straight up impossible to win. Ex: Your bot goes 0/10 in the first 10 min of the game (unwinnable) (out of your control). You got both other lanes roaming around and pressuring without control because your teammates straight up cant even get close to them without dying (unwinnable). So its all about the win ratio. You win some u loose some , and if your good you win more than you loose and ultimately climb.
