I struggle to carry as Swain midlane in silver 3 despite winning lane consistently.

Hello

I am a new Swain player on midlane. Previously i was playing as Yone and Diana but they are much riskier to play efficiently, especially as a blind pick, which happens very often in my games. Before Swain i had 55% winratio but after 4 matchups as him i have 52% winratio now.

I was winning on my lane in my most matchups, even against two Fizz players from Gold, but my main problem are teammates who are feeding the lanes. For example in my one matchup against Fizz, where i was winning my lane i had 0/10/4 Samira with 1/8/4 Rell against 11/2/9 Draven and 7/2/15 Pantheon, or Garen who played well but he had a good Mordekaiser against, who made him struggle at lane.

Luckilly for me for my two lost games i didn't lose any LP, beacuse in my one game i had an AFK teammate, and in another i had a support Nautilus who was trolling in early game for roaming everywhere. Reporting him was very useful, beacuse riot gave back my LP.

According to porofessor from these ranked matches i have 5,6 CS/min (I know this isnt very much, but had to roam a lot to help my teammates. Although in early stage of the games i have higher CS/min than 5,6), 54% kill participation, 383 gold/min, 1,000,4 damage dealt/min and 0,6 kills + assists/min. The Average KDA is 8/7/8.5.

About builds, i usually start with Blackfire torch -> Sorcerer's shoes -> Rylai -> Liandry

If anyone wants to check my OP.GG i am putting my account's link before:

I'd appreciate any help, even the most honest and brutal ones
