A couple things I've learned that seemed to make me a better player..

I'm a pretty emotional person irl, so it's only natural I've always been emotional on video games. Once you have your mechanics in league.. and you get how to play a champ.. it's really just knowing variables and fundamentals. (When not to overextend, , etc). but I've found that I've made myself a much better player when keeping myself as far away from toxicity as possible. Let me define toxicity real quick. It's not what I define as toxic, or what Riot defines as toxic. It's what YOU define as toxic. Riot won't make you a better player. I won't make you a better player. Whether it's flaming, or negative pre-game chat, or someone playing like complete shit and taking it out on the rest of the team. Whatever you see as toxic.. that's what I'm talking about here.

The climb is a dangerous thing for the easily angered. Mute button is OP. Seriously. If someone is giving you a hard time, and you feel it's not being conducive to the game or benefiting you in any way, just mute the fucker. You'll forget they exist. Let them vent at you after the game. The most important part here, is you keep your head off tilt. This game is truly never over unless they're up 20 kills and you have no objectives. Keep yourself off tilt, and work with the people on your team who aren't toxic.

Complimenting other people where they do things right, even if it's the other team. It's not seen enough in this game. Too many times people do things right and get one gj from someone, but they don't realize it could be a turning point in the game. Where you think you can find a chance to tell someone to keep doing what they're doing, they're more receptive to telling them things they shouldn't do. If they respond in what you would deem to be toxic, MUTE BUTTON OP.

Don't give the angered much attention. If they're on your team, tell them once to relax, try to help them find a solution if you have the resources. Just because they're getting mad won't solve the problem they're having with their opponent. If you want to be a team player, communicate and see if you can find a fix. Don't let it get out of hand, or things will go sour and the mute button will be needed. If the situation literally cannot be remedied, you should focus on your objectives and keeping the rest of the team on track. Someone will die a lot - it happens in every game. They're already feeling like crap because they're feeding, and they're easily picked off when they have no kills. That player from this point in the game should be more like a decoy in your mind while you get yourself (or whoever needs to get fed) bigger. Once the entire team starts contributing in fights on a normal basis, PROVIDING YOU DID YOUR JOB AND GOT YOURSELF FED/SOMEONE WHO NEEDS TO BE FED, that player will start to get kills and have more opportunities to CS and catch up. If they keep diving in and dying immediately, they are a lost cause outside of your control and you should focus on the rest of the team. Even at this point, stay awayyyy from the toxic.

TL;DR:

1. You need your obvious mechanics. When to dive/when not to dive/map awareness/wards/etc
2. MUTE BUTTON OP.
3. There's not enough positivity in league. When you see someone do something right, like maybe they're setting themselves/you up for something.. communicate and let them know you acknowledge and hand out GJ's more often. Things like getting someone low and making them back, or making someone burn a summ, or pinging a heads up on someone coming your way.
4. MUTE BUTTON OP.
5. When you're pointing out things people do right, they're more receptive to when you point out things they do wrong.
6. Don't give those who are tilting much attention. Try to calm them down, and fix the problem. If things don't work out, MUTE BUTTON OP.
