The problem with your statement is that league is a game not easily taught, you could play with the play players and they could tell you your weaknesses, but honestly if they left you wouldn't be able to improve on your own. That's why people always say to get better you have to "play the game" and I get that frustraing when a Annie top auto locks and feeds 20 kills in 5 mins, but that doesn't stop you from learning what to do when behind. As well playing at your own level is still something you need to do, it just means you have to push through that mmr. Finally, you should try to trust our team mates, climbing through silver in season 6 there were some badass silvers, got carried by a ad jungle once. I'm not saying I'm good at the game, actually I'm far from it, just my personal opinion on the subject.
