Is my champ pool holding me back?
For the last 5 seasons I've swapped around between maining Top/Mid/Jg and have never had a problem hitting gold. I did actually get Plat a couple seasons back, and I'm pretty sure the main reason I haven't replicated that is because I haven't played enough games in ranked each season.
This season though I did a complete 180 and decided to try maining ADC (Which I have very minimal experiece with). After playing a number of normals in the role I finally felt confident enough to bring it into Ranked. As soon as I did that though, my win rate absolutely tanked. I dropped from Gold 3 to 0 LP Gold 5 very quickly. While there have been a few games I threw because of bad decision making late-game, in general I don't think I've been complete dead weight to most of my teams.
The main champs I've played are Varus, Jinx, Ashe and Jhin with a smatter of MF and Trist. I know that MF, Ez, and Trist are basically retardedly overtuned right now, but does my main champ pool seem like trash for this meta? Am I taking on too many champs at once for a relatively new ADC main? (Also, my recent Varus winrate is abysmal because I tried to copy a lethality build I've seen in high elo, but I can't pull it off. He is probably my best champ for the role atm)
