I created a second account to play with Silver and Bronze friends. I will say, those are some of the most frustrating games I have ever experienced in league. I half regret creating the account, because the grind was long and tortuous to get to level 30.
I think I got use to Gold players simply rarely making really obviously bad plays. Low silver and Bronze players make several mistakes per game and do not react the same way when it comes to objectives.
They also tend blame others more often, even though they make equally poor choices in-game.
It is nice having a smurf account in which I don't care about my rank, but at the same time those games often give me headaches.
Games are just thrown so much more often. It also puts a lot of pressure on me to hard carry a game. There was one game recently I played, which I felt I did everything I could to win the game and we still lost by a LARGE margin because the bottom lane fed really hard.
I need to take into account though, that I was really bad around this time last year and made A LOT of terrible mistakes while learning the game.
I got significantly better, but some of my friends are still sitting in Bronze or low Silver and they have played the game for years. It simply means they have hardened some of their bad habits and/or they do not have much prowess in executing skills in the game.
I wish it was the latter, but typically it is the former. My friends that have played the game longer than me, are even less prone to listening. I have only played the game for a little over a year, but I have a better understanding of it than most of them.
