Bronze to Plat in one season
I remember season 3 when I started league of legends I mained jungle Elise. Mainly because it was the most popular jungler in the LCS. the problems that I had with my season 3 ranked play though, was that I was only good in the jungle, and I was a burden to my team if left into any other role that wasn't jungle. Season 4 I sought to improve my versatility by playing in different roles, mainly bot lane. Season 4 I was bronze but managed to start learning a little bit more about stutter stepping, learning to flash crucial stuns in 1v1 scenarios, I found myself trying to outplay anyone that crossed my path even if it meant going against a fed cass as a feeding vayne. I would like to call this phase: learning my limits. It may have been feeding but it really helped me learn what I could and could not do. Take your time when you play and after every death literally take a second and try to understand what went wrong, don't flame and blame your support, everything was on you, if your thresh didn't land that hook you made the mistake continuing to go in. At the end of season 4 I was frustrated because I felt that I had the potential, I'd watch videos and tell myself I could do that if my team would just not feed and let me carry the game. But as soon as I turned to the replay system my view of the game changed dramatically, I began to notice obvious mistakes, like making it to lane late, missing easy farm, overcommitting for poke and taking Aggro from minions. It really sounds tedious to replay a game from start to finish only to watch yourself lose but you seriously learn a lot about the mistakes you made, and you won't be making them again, you'll go into a game and tell yourself I have to watch out of this cc, that cc and etc. A huge improvement to my game was watching pro streamers. Yes they are very entertaining but do not take the advice they occasionally give lightly, ask yourself even when you're watching double lift or faker play on YouTube, "why did he do that?" Again "WHY DID HE DO THAT???" This is the way out, I'm telling you, I would constantly flame in games and the one thing it does is keep you from asking yourself "why did he do that, where did I go wrong" season 5 was a steady climb to platinum but there were some rough patches along the way, just learn that in every Elo there are toxic and bad people, Gold is no heaven, platinum probably the worst, the solution to all of them? Just press mute. I would highly advice taking a break after going on a losing streak, trust me you may be on tilt and taking the time to rest and get your mind off the past few games is very beneficial to you. Good luck on the rift summoners!
