How do I climb the ladder?
For the longest time I've had problems climbing the ranked ladder. I'm really not bad enough to be in my current position. I main adc or mid, I have good positioning most of the time, I farm well unless I get shit on in lane, and my lane phase is generally good. I also call mia's and try to be as nice as possible and ignore the trolls. But regardless of all of that, I still have problems climbing. Why? Every time it rolls around to teamfight, my team doesn't know what to do most of the time. Tanks just stand there instead of engaging when we have the advantage by catching somebody out of position, or we don't push to take a turret out, or some other squishy from my team tries to #LCSBIGPLAYS and then they get caught out before any of us realize the bad decision they made, or my team engages 4v5 without me or another person from out team. And every time this happens, we loose the game from sheer ignorance of how to teamfight.
This has happened to me so consistently that I've recently gotten discouraged and stopped playing ranked almost all together. I hardly play one ranked game a day, if even that. With the LP drain and the consistent loss streak, I've gone down from S3 promos to S4 with 8 LP. So, to any seasoned ranked climber out there, how do I fix this? Is this just bad luck and I need to play a lot more, or is there something I'm doing wrong?
