if u wanna climb, a good suggestion is: be positive, stop being toxic, & the system will reward u

by the hidden rule of human communication, if u are nice to someone, he/she will be nice to u; however, if u are angry or taking to take advantage from someone, he/she will do bad things to u.

and every single system will try to reward someone who is nice to other people; & punish the ones who did damage to others. so as the league.

if u are a toxic person, the system will match other toxic & someone who has intentional feeding allies to u; however, if u behave nicely, the system will match nice guys to u. that's the way of how human beings work.

so if u wanna climb, train up yourself to behave nicely to others. u will not win every single game, but the system will definitely reward u by winning more games.

edit: of course u need to get good on your game knowledge & skills (macro, micro). being nice would not automatically gives u free win. u have to work on your own skill as well.

if u want something extra, then try to be nice.
