Champion reccomendations for each lane/role?
Right now I basically have one champ that I "go to" for each role, but I feel like I should at least have two more options in case of bans/other issues. I also used to play a whole slew of champions who I no longer feel comfortable playing (Mordekaiser) so that's also sort've "shortened" my list so to speak. Champions I usually tend to pick are
Top - Shyvana Mid - Ahri, Zyra ADC - I barely play it due to lack of comfort, but when I fill I usually take Tristana if she's open Supp - Sona, Zyra Jung - Another role I rarely play, except in this case I don't even really have a "go to" champion. I usually pick J4 or Xin when I fill this, but I'm not that competent at the role
