I looked at your stats. They look pretty good. I figured you were embellishing a bit regarding the stats.
Some trends I noticed by glancing at your stats:
- You play too many champions - try to get really good with a couple per role
- You play too many roles - Pick 2 or 3 roles to play ranked in. That's it. Stick to that. Dodge if you don't feel comfortable with the role you get.
- Your CS per game is low or on the lower end - You KDA is good but the CS average per game with some champs is about 20 or 30 lower than it should be. Focus less on killing people and more on CSing.
- Carrying from the support role is hard in lower Elo. You could abandon the role completely or continue to play it, but I will tell you that supporting in Silver is hard. Your ADC will be all over the board in terms of skill and most support mains are better than their actual ranking.
Other things I noticed. You play a lot of Lee Sin relative to other champions. This champ drops off and if you team does not end the game early you become less useful. You may want to main a different jungler whose utility and damage improves as the game goes on. You will be in longer games play in silver. The same can be said with teemo. Teemo is an early pressure split-push champion that becomes increasingly ANNOYING as the game wears on, but drops off the longer the game goes. You may have success in lane with him but this may not translate to wins.
Your Darius, Ahri, and GP all look good. Keep playing them. Your Jhin looks good as well, however, your CS average per game is WAY too low for the role. This tells me you may win lane but do not focus on pushing your lead. You should be floating close to 200 per game at least as the ADC.
Your KDA is high with several champions, but you also have a lot of deaths. In fact your KDA is a bit deceiving because on several of your better KDAs you still die as frequently as you kill, you just participate in a lot of teamfights. This is most noticeable with your support roles. Not saying this is bad, just saying you may want to focus more on limiting your deaths.
