My two main champions for **each role **so far are (primary to secondary.)
Midlane is 
Toplane is 
Jungle is 
ADC is 
supports are 
Would anyone be able to help me find out something for a third champion in each role? Thanks if you do, I really appreciate it!
Sweet Katarina1 votesKata, Darius, Rengar, Jinx, Morgana/lux/blitz (too much good supports)
Bravoh1 votesIf you want to get better you need to play someone harder to play. Each role has a variety of champions you can choose from that fits many play styles, so it would be really good if the champions you main are different from each other. Like your mid, you have a ekko who is good as early game damage and a viegar who is great in the late game, you should add something that would be good in the middle game.
mid - 
jungle - 
top - 
adc - 
support - 
I tried to pick champions from each tier of cost
Privileged Jew1 votesSeems like for the midlane you enjoy both high-mobility assassins and low-mobility mages.
Might I suggest, then
