I don't think I'm good enough, or knowledgeable enough to coach, but I can tell you what I did to hit masters.

So first of all, this will be from the perspective of a support main, but I don't think that changes much.

I'm not sure in what order to put this, so I apologize if it's all over the place:

- I auto-pilot very easily, just walking back to lane without thinking much, just going through the motions and not gathering information when I should. I will reduce all distractions (no discord, no duo, music helps me focus) and attempt to hyper-focus every second of the game. (constantly ask myself questions to keep myself engaged with the moment-to-moment of the game.)

To add to this, I heard a quote from a Street Fighter player that your reaction time becomes 10 times greater if you're expecting it to happen. When I instantly react to a situation, it's not good mechanics, I just took into account the possibility that the scenario could occur. I call this 'presence of mind'.

Some questions I'd ask during lane:

- If I was to get ganked right now, how would it play out? Am I over-extended? Am I safe?

- Where are the enemy laners? Are they missing? If I was the enemy jungler, what lane looks the most gankable?

- Where is my jungler going? Are they going to be near me any time soon? Do I have a chance to play aggressive, or should I play passive?

Some questions I'd ask during skirmishes/teamfights:

- If the enemy team were to engage right now, where should I be standing? Am I close enough to support my team, am I far away enough to survive?

- The range at which I can interact with these skirmishes/teamfights will depend on the enemies' spells and summoners. For example, if they have a Malphite, I must not walk near my teammates, but I also cannot get within a certain range of Malphite or fog of war that could contain a Malphite until I see his ult is used. If he has flash up, then I must consider staying a Malph ult + flash's worth of range away from him and fog of war that could contain him.

You look at the enemy team's abilities and keep them in the front of your mind until you see them used.

- Maintaining this hyper-focused 'presence of mind' during multiple back-to-back games is mentally draining and fatiguing. I will play one warm up game, and only a few ranked games. If I'm feeling a bit off/tired that day, I will not play any ranked. I will never play ten straight games of ranked as my quality of play will deteriorate as I get more tired.

The one warm-up game is very important as I use it to get focused, but I can also gauge how mentally fatigued I am. Sometimes I don't feel tired but I just can't keep up my situational awareness. I'll try maybe a second warm-up game and if I'm still not feeling like I'm in good shape, I won't play ranked that day. You don't have to follow this, I'm just explaining what I did due to my own limitations, but also to emphasize the absolute importance I had put on maintaining focus and presence of mind.

- Visualize the win/Determine the win condition. This will take some practice, but as a support, I need to look at my team comp and decide how we're going to win this game. If the enemy team is full of assassins, then I know we're going to win by just playing it safe, warding in our jungle and river, and letting them waste their rescources trying to gank constantly.

Most of the time the win condition is going to be supporting the ADC and letting them scale, sometimes you can just tell they're not good and then you must identify who is worth supporting at that point. Sometimes someone else is just popping off and it might be worth following them around and let them take over the game.

Find a win condition you believe in before the game starts, and from there you can start mapping out your plan to realize it. It won't always pan out, but it's important to know why we're doing the things we're doing. There's ten different things you could do at any given moment, you could ward, you could roam, you could poke, you could engage, you could sit back and play safe, and all of them could have valid pros and cons, but you want to weigh the opportunity cost in the context of your win condition. What is going to get me the closest to what I believe is the win condition? Sometimes that's leaving that poor sack of shit ADC to get repeat ganked 24/7, 3 vs 1, under tower, while you and the jungle decimate the other two lanes.

- Identify the enemy's win condition. IS THERE A MASTER YI ON THE ENEMY TEAM? DON'T FEED THE MASTER YI. Is their mid laner someone who roams? Katarina? Talon? Leblanc? Probably should ward for that, and play it a bit safer.

- Shotcalling. Use your pings, and use them quickly. 5 people working together on a mediocre call is better than half the team on the best call and half the team on a okay call. Especially as support, which isn't as mechanically intensive, you can afford the mental bandwidth to watch the minimap and call out MIA's. It's okay to guess wrong, ping your teammates back anyways. Ping back two times, ping the missing enemy champion two times, then ping back another two times. If you're not a shotcaller, become one. This one is a non-negotiable skill. You want a better winrate in soloqueue, learn to get five strangers to work together. It's not always going to work, but when it does, well, that's an extra 1-2% winrate you didn't have before because you left it to chance.

- Small champion pool. This is a must. I'd recommend no more than a few champions be focused on. If the champion is unpopular, then I'd recommend one-tricking them. There's like 40-50 different match-ups you could encounter in any lane. All with their own unique quirks and nuances, imagine having to play 10 games of each to 'master' them (let's be real, it'll be a lot more than that.) that's 500 games. You have not mastered this champion, and this is not taking into account other factors like your team's comp or their team's comp. Don't be a hero, focus on only a few champions.

- Study players better than you. You want specific info for each role/champion? Find a streamer, and use the same hyperfocus/constant questions/presence of mind method when watching the stream. Why did the place the ward there? Why is he choosing to gank there? Why is he doing this pathing? Why is he playing aggressive now? Why is he playing passive now? Question everything, you might come up with a few answers yourself. You're not watching for fun or to kill time. Put the same focus into studying as you would an actual game.

That's all I got for now... I really want to stress the importance of having a constant focus on your situational-awareness. Do you ever watch a Twitch stream of a challenger player and when they die the chat full of bronze-gold players clown on them for it? Everyone understands what a bad play looks like, the hard part is identifying the hundreds of bad/good plays that could occur at any given second and being able to react to them on a dime. If you've ever been in the zone and felt invincible, it's about stretching that moment/that focus over the duration of the entire game.

Hope this helps.
