I FINALLY MADE IT OUT OF SILVER
I straight up hated silver. I feel silver is where your everyone is bad enough to cost you the game but good enough that I can't straight up crush my lane constantly and just hard carry.
In no particular order Vison (especially around baron), strong picks or at least champions your really good on, proper itemization, understanding champions strengths and weakness, map awareness, watching for level 1 invades/cheese (not sitting at tower or base like a monkey), not playing yasuo or wasting a ban on him ( I personally ban Gangplank or Fiora because they can actually 1v5 consistently and luck is what I truly believe are the bare minimum needed to get out silver. I consider these the basics of league that can win or cost you games if lacking in any area. I recommend playing mid and top where I believe are the best roles for carrying/winning.
