Easiest way to get out of bronze: learn to last hit
So I was playing on my bronze smurf account and I decided to try something. Normally when I play on my smurf I just kill whoever I'm facing in lane over and over again in order to get fed and carry. But I realize that this is not something that everyone in bronze can do to carry. The reason that I get lots of kills is that my laning mechanics are alot better, but another bronze player probably couldn't get that fed.
So I decided to try something. I was playing top lane jax vs renekton, and I decided to not try kill the renekton, I just focused on farming. I used my stun defensively to avoid getting bullied early, other than that all I did was last hit. I even died to renekton once ~5 minutes in when their jungler got a good gank on me. However, at 12 minutes I had 110 cs while their renekton had 40.
That's 70 cs difference in just 12 minutes of play. Even though I died to renekton once I was a level and an item ahead of him. If 18cs = 1 kill then I was almost 4 kills worth of gold up on him. I then killed him in lane and he raged about how OP jax was, and his exact words were "so fukin bullshit that you can just kill me while you're behind". The renekton actually thought he was ahead in lane just because he killed me once, even though he missed out on 70 cs. This is the mentality that keeps people in bronze. You need to realize that kills are actually unimportant in low elo, and that the effort you put into trying to get kills could just be put into farming instead, with much better results.
EDIT: I'm not trying to say that better CSing is the only thing wrong with bronze players, or that every bronze player is bad at CSing, etc. I'm just saying I notice a very clear pattern of people in bronze thinking that kills are the definitive answer to carrying games. If your lane opponent is harassing you, trying to kill you, and missing cs while doing it then you don't have to harass back and try to get a kill. If you just focus on not dying and hitting cs you will get ahead of them. And if you get 18 more cs than them it's basically like you killed them. Minions are alot easier to kill than champions guys!
