How to get out of Silver?
I've been in silver since I started during the summer, going from silver 3 to silver 4, back to silver 3, repeat. I really do not know how to climb now. There's either afk's/trolls, errors or just plain unskilled players. I do not by any means believe I am better than the majority of silver players, and I know I have a lot to learn, but I really do not know how to advance with some of my teams. Countless times have there been issues with communication, such as no one warding even when asked, backing away from a fight, etc. I can only do so much with a team that refuses to listen or learn from past mistakes. I try my best to avoid making the same mistake twice, but I cannot speak for others. Each game I do attempt to try a little more than last game, such as ganking more often or helping a lane get fed. I also attempt to learn from games I lose, such as how an enemy team wards or synergizes with another member. Right now, its a pattern of bad-good-bad-good, or a few goods then a bad, a few bads then a good. I'm slowly getting closer to silver 5, and I really wish I could just get higher instead of lower. So, any advice? Thank you!
