I don't think improving is essentially possible.
Without being genetically disposed for League of Legends intellectually (in terms of pattern recognition, emotional stability and extrapolation based on limited information) you pretty much aren't going to improve very much.
Most people in the world are mediocre and they stay mediocre for their entire lives. Most people in the US are lower middle class or below, with 50% of the wealth being held by the top 1%. Only 25% of the US population has a bachelor's degree. Now having a college degree may put you in the top 25% of educated people nation wide, but surprisingly, knowledge is distributed much like the elo scale: a bachelor's degree is merely the entry point, and if you want to become someone who creates new knowledge, you need a masters and PhD. The knowledge level of the typical masters graduate is far greater than that of a bachelor's in the same field: the difference in knowledge between a masters and a bachelors, is roughly like the difference between a middle schooler and a bachelor's. The difference between a doctor and a bachelors, is the same as the difference between an elementary school student and a bachelor's.
This is exactly like the elo scale. Being gold is great, you are among the top 25% of the ladder, but in terms of skill, you are like a college graduate and just scratching the surface. Most people are bronze and silver. They want to improve, and don't know how... but that might be because there IS no way to improve. It'll be like asking a high school dropout, why are you poor, why don't you just go to college? why don't you just pick up a book? Why are you so lazy? The truth is, they might not have the ability to do so.
What about the people who go from bronze to diamond in a few months? Who are they? Well, they're people who are genetically predisposed for greatness in league but just got off to a bad start and established bad habits, just as elite families who lost everything in a crisis often rebound.
What about those who rise and then tilt back down? In my opinion, that's like the people who got rich from the stock market then lost everything in a crash. They weren't good at stocks, they were bad, but lucky.
What does this mean? There's no point in trying to improve. You'll naturally be at a certain level after a certain number of games and then you're done. If that happens to be bronze/silver, you might think its elo hell. But it's not. You'll just have hit your natural genetic limit.
Just remember: most of the people in challenger now are the same people who were in challenger back in season 3. Do you really think improving beyond your limits is possible?
