The best role to rank up?

support has the highest chance to climb in any elo over silver. if you master the role you can out ranked your friends in solo queue.

something u can carry with so either adc, jungle dont listen to them support is the hardest role to play and if u dont have good adc there is no hope .

nothing depends on the role, the main thing is to understand the basic principles of the game

if you really want to improve and rank up you should learn at least one champion x lane. then play in jungle. Knowing how to play lane will find it easier to gank.

Probably jungle is the best role for soloq climb, combined with Mid duo it's hard to stop, for example, equal level Mid/JG vs Bot/Sup in low elo definitely the mid/jg duo is winning that
