Tips to climb for League of Legends

Don't focus on trying to rank up fast. Focus on improving your mechanics and game knowledge. You will naturally climb if you're playing better than the people in bronze. If you've been stuck there for 3 years, it means for 3 years you haven't improved at all. You should be playing ranked to get better and that will be shown when you're climbing. There's no secrets to climbing. Just by getting better you will climb on your own. I suggest after every game try to figure out mistakes you made and what you could've done better. If you can't figure out what mistakes you're making find a good player and have them watch your game and tell you your mistakes and what you could've done better. Also, don't have a mindset that bronze is elo hell or that your teammates are holding you back. Your teammates can flame, feed, etc but you shouldn't let any of that affect how you play. Hope I made sense. Good luck ~
