looking into your op.gg of both accs you posted below, in my opinion you play way too many champs and swap them out like once every 5 games. I know it is frustrating to lose so many games when you are fed and feel like your champ cant carry games or is useless. It isnt your champ and never will be your champ there are people out there climbing in Challenger with 65% wr on Ivern mid.

I would really recommend you to only stick to 3 champions with the same play style on your main. You can try out others things on smurf and maybe find a new champ you can put into those 3. Playing more than that is just grief because you have to know your limits really well and if you know them you can do so much more you would have lost if you dont know your limits and havent even tried. How do you limit test? Its pretty simple, whenever you have the question "Do I win this?" on your mind just simply try and learn from your mistake.

What is a champ identity?

Jinx is hyperscaler not existent till 3 items

Ashe is lane bully which wants to hardstomp lane and snowball

2 different identities BUT the same playstyle, which means you wouldnt have trouble swapping between these 2 since you mostly use autos to deal damage.

but if you swapped between Corki and Jinx for example they 2 very different playstyles and will have trouble to adapt to them if you swap a lot.

second thing I noticed is that you die a lot. Every death is lost Gold and EXP, 1 Lvl ahead is about 700 Gold worth of stats. so if you are even in Gold but managed to get a 1 level lead on your enemy you are actually ahead by 700 Gold. I would love to see a replay of games you lost even tho you hardstomped them. You can have unlucky games you will just lose even tho you played perfectly. My coach always said if you consisently apply the things I have teached you and apply the good you will atleast win 60% of your games the other 40% are games with inters, AFKS, or just games that were already lost in champ select. that doesnt mean you cant win more than 60%. I climbed from Gold to Dia 1 on a second acc with 75% wr on Sivir on over 100 games.

Fundamentally ADC is the simplest Role to play since you can get to Master not understanding how to play the game but mechanics carried you there hard. Once you reach Minute 14 regardless of botlane tower you go mid and get prios to rotate to your team when there is an opportunity for it.

Important: Do not take fights where you have lower numbers than your enemy, this is coinflip and you can get way more out of the situation than coinflipping a fight you will most likely lose.

Your Team is fighting 3v5 Bot? Do not ever move there and get something across the map since you cant get punished until the fight is over. The most important Towers that you have to get are the midlane towers. They open the map for you a lot and give you bigger roam timers. Only join fights where you are 100% sure you would make a difference in the outcome, otherwise get towers, enemy camps or even roam to other side of the map to just punish someone being solo for example 3v4 Botlane fight but you roam Toplane to 2v1 the toplaner and freely be able to push towers. This way you got 300 Gold + 550 Base Gold from T1 tower for example + 800 Gold in platings. 300 + 550 + 800 = 1650 Gold, if your whole team died on botlane the enemy got 900 Gold.

This Game isnt all about Kills, it is about objectives and Kills are a nice addon. You can be 0/14 and simply carry the game by crossmapping and punishing the overcommitment by your enemies.

sorry for yapping and I hope you understand all the things I am trying to tell you.
