I started ranked in Season 3 the moment I hit level 30. I've played almost exclusively ranked since then. It was a long hard slog out of bronze. Looking back, I can see all the things I did wrong that kept me there as long as I was. I peaked this season at 80 LP in Silver 3, and I plan to get Silver 1 next season. Set realistic goals, and always try to improve your play.
There will always be games that are out of your control, but the proper attitude is "what could I have done better," not "that feeder mid made us lose". Even it's true, because that attitude doesn't help you improve.
I went over a game with a coach, he pointed out ways I could have been better. Then said, "I know we shouldn't blame teammates for losses, but Diana really wasn't helping at all. She fed your lane, she fed her lane, and was always positioned badly. But here are ways you could have tried to help her..."
Don't insult your teammates, even if they're really bad. Insulting someone doesn't make them play better, and might make someone who likes to troll start doing it in earnest. Suggest improvements politely. "Leona, please get a sightstone. We need more vision. And everyone else, upgrade your trinkets." This works way better than "Fuckin' noob Leona won't buy a sightstone. Idiot." She might still not get a sightstone when you're polite, but it's even less likely if you're not.
Anyway, good luck out there.
