Need help proggressing
Where do I start, I have reached a point in lol where I am starting to tilt very hard. I did really well climbing my way to b2 and b1 but the competition is different. I am now facing opponents that are really decent at the game and can communicate decently enough where if i get a lead i expect to get camped by their jungler stopping my snowball. Most games i feel like i have lost cause of my performance.
I am trying to learn by watching the pros and playing different adc's to counter different adc's to get me an advantage and learning what they are best at. I have been focused on cs'ing and maintaining gold leads throughout the game.
But i am having a hard time being the driving force in getting my team to win if they fall behind.
The skill level of my champs in succession as fallows

i have learned their strengths and weaknesses but im having a hard time applying it when in game. Usually i try to make a play no matter how bad my team does we will come out on top. But its hard finding such opportunities unless my team has good follow through and map awareness.
If someone could point me in the right direction and maybe spectate one of my games i would be very appreciative.
Thank you and have a nice day Sakeial
