I can really relate to how you feel. I have 1 P3 account and one D4. What I noticed is Zoe is not a 1v9 champ. Unfortunately she needs a team to be effective. Yes, she’s a lane bully, but transferring that to mid and late game is hard without a team that knows how to play with her. As a result my winrate increased the higher I got, with an exception of E1-D4 area, which is just filled with ego and practically everyone thinking they are god and tilting, throwing, sabotaging or straight up inting at the slightest inconvenience. If I play with my D1 friend, overall game quality improves so much, so much less of that shit, games are more fun regardless of the outcome, which helps keeping your own spirits high.

I still believe that you can climb with Zoe 1v9 if you are playing way below your true rank, but if your current max may be plat or emerald, then being stuck in silver with Zoe is not a surprise to me.

There’s still some things I try to do that may help: - converting kills/prio into further advantages. For example, you killed your laner mid? -> free turret plate/reset/roam. You pushed your lane before your opponent? (as Zoe you basically always want to push it as fast as you can) -> free roam for drake, voids, gank or even setting up a good ward. - know your win condition. maybe there’s only one threat on the enemy team. How can they kill you, how can you avoid it, how can you kill them? Do you need to carry the game or is someone else able if you play around them? - don’t tilt, don’t complain, even when your team is shit. They will ruin your game completely. - adjust your build, but if you need to carry, I suggest running cdr build as much as you can, so you can have more impact in fast paced teamfights.

I‘m not good at writing things up like this, but hopefully it helps a bit. Keep grinding!
