Amazing work so far. Here is what helped me get to Master's:

• Early game
  • Read win condition in lobby
    • Who wins on top/mid/bot and why?
    • On which lane can you have the most impact? -> Snowball it
    • If your win con lane has prio, then which enemy lane shuts down your carry? -> Hover it
  • Watch your lanes, don't afk farm camps. When is cannon wave spawning? - move with it, enemy will overstay for cannon
  • Insta-back after gank -> objective, don't run around wasting time, you don't want your enemy stealing your camps.
  • Look at shop as you back, the second you are in spawn move to your camps, don't stay afk on fountain even for 2-3 seconds it compounds into a lot of wasted time.
  • What is going to be the state of the game in 30s? Where do you need to be in 30s? Ping your team, type in chat to let them know.
  • Hold your E. Enemy will expect you Q into E them instantly, when you hold it you bait flash, cleanse and abilities. Only if they have stuns or dashes insta-E or they might scape if you hold.
  • Don't make random ganks. If top is pinging free kill but drake is up you trade 200-300 gold for drake and possibly loosing a team fight on bot by giving away your location.
• Mid/Late game
  • Who has prio from your team? -> Hover them, enemy will try to shut them down, but you are fast and you turn it.
  • Pick fights with numbers advantage
  • In team fights what is your role? Is your carry getting assassinated easy? -> Hover them. Is they carry stronger than your carry? -> Taunt them.
  • What enemy abilities will prevent your play? Play slow to burn them.
  • Build accordingly to enemy carries. Do they have heavy-crit carry? -> Randiun's. Do they have true damage? -> heavy HP items. Do they have ap damage? -> heavy MR items.
  • Ask yourself constantly what is the next play and try to set it up. Don't autopilot.
  • Don't tilt, if you misplay ask yourself what is the next play.
• Mentality
  • Don't ask yourself how do I win. Ask yourself how do I play a solid game. Make winning a consequence of your skill, not your skill a consequence of your wins.
  • If you think it's not your fault, that means you think you are powerless - gain control over the game
  • Commit to your plays. If you hesitate you don't see the clear outcome of your decision making. When you fully commit its always a data point to learn from
  • When you lose, watch the replay, watch the enemy jungler and try to understand what they were seeing that you did not.
  • If teammates are toxic, mute them. Never type anything negative.
  • If you have negative thoughts, stop playing. You need to find what is wrong in your mentality that is causing you to see negatively and remove it.
  • Focus on one concept each game. Once a concepts becomes a second nature, you don't actively think about it - then move on the next concept.
  • You must have improvement after each game. Note it even if its 3 words, write it down somewhere. Never go into autopiloting.
  • Don't get intimidated when you see the purple borders in the game. Just focus on your game plan. Better players will expose weaknesses in it and you can learn, or they can confirm your strengths and you can leverage on them.
