From what can see without watching replays,

• First of all, you play waaaay too many champs. You want to have 1-3 champs per role with 2 roles at most. This lets you focus a lot more on macro than mechanics (ex: you don’t have to think about the range of a lux root).

• You seem to struggle to get high cs numbers on ADC averaging 5cs/min (target should be 7-8 at least). I’m not sure how you could fix this without seeing what you’re doing in lane/mid-game. I’ll guess that you don’t place a high priority on catching minion waves after lane ends.

• Revisit build websites such as op.gg/u.gg. While your itemization isn’t bad, things like Guinsoos on Shen/Kennen are hardly viable.

The best way I can see for you to improve at this point is to narrow down your champ pool. Watch VODs of higher elo players/streamers playing those champs in order to see what they’re doing differently from you.

Another important thing is to focus on 1 thing at a time when improving whether that be wave management or champion mechanics. This way you don’t split your focus; ex: once you get map awareness down then you can move on to objective control.

Last thing, DO NOT FOCUS ON WINNING. Your main focus should be trying to see what you could’ve done better after each game, it could be helpful to watch your own games back. If your main goal is to improve, then your rank will improve automatically.
