simple tips to gain you elo

Rethink your champion choice if you do less damage as an adc champion than an entire team that went 8-28 does.

Dont help the feeding laners as a jungler help the winning lanes

Play easy champions till you learn the game. Not like "riven, yauso ect" more along the lines of annie,nunu,trundle,garen,ashe,lucian ect, and you havent learned the game if you cant even break d5 lets get that out there. Too many people say "i know how to play" yet they cant get to a midway point like d4 d5 so no you dont or well you would climb obviously. And no you dont have the mechanics to play zed ect if you did you wouldnt need climbing advice you can get to d5 off of mechanics alone.

rotate and Spam the easy champions. 10 games of one champion then switch. Dont play more than 3 champions in a role and 4-5 champions in total (aka secondary role and primary) You might lose until you learn the champion but you will climb faster and learn more on the easy ones.

Play to help your team but play logical. If you are in fact someone who can do good play damage roles that can impact a game and help the team you should be able to carry the fights if you position properly or catch someone out. Dont play support if you are trying to climb. But if must play carry supports like ap zyra,lux,ect.

Do everything for a reason. Dont just do things blindly know why you do things.

Use probuilds for runes and masteries. You dont need some in depth stuff just do what the pros do and it will work out better than some mobadfire guide.

Play more. The more you play the better you get. Cant expect alot of results with 1-2 game a day over someone who plays lets say 10 games a day.

Try to keep a good mentality. Solo que is a pain in the ass do whatever you gotta do to be calm and just think to yourself that no matter you should be able to carry the newbs and try till the end and you will prob win more often then not.
