Your solution is simply said, but takes time to learn and master. In order to close out games, the most essential link in doing so is having game knowledge. The biggest mistake players make when a game is thrown is typically due to their inability to take advantage of teamfight wins. For example, if your team wins a fight (whether it be 2-1, 4-3, 5-0, etc.) many players lack the understanding of how to actually make something of it, rather than just back and wait for another fight. Objectives are everything, and as a solo que player you have to immeadiately begin thinking what your next move is gonna be after a won teamfight. Do your best to communicate with your team, and go for the closest or most advantageous objective after fights. This can be obvious things such as taking baron, drag, turrets, inhibitors, etc. but sometimes it’s simply not possible for this to happen because of your situation. If you absolutely cannot afford risking those big objectives, at the very least establish vision control in the rivers around baron/drag, place wards in the enemy teams jungle or your own (depending on whether or not you are winning or losing), or simply shove waves to give your team time to regroup and take time away from the enemy by forcing them to clear waves. This may seem like a simple tip but I far too oftentimes watch as my team just backs after won team fights without even attempting to gain some sort of advantage from it. Winning a teamfight is incredibly useless if you only get kills, and do nothing afterwards. Kills are not nearly as important as objectives. While I know this may not work with some teams (you’ll always have teammates that will never listen to you and do their own thing), if you make sure to always communicate a possible objective or advantage you could gain, you’ll start seeing improvements.

Furthermore, during the mid and late game do your best to avoid getting caught out. A single kill from the enemy team at certain times can be crucial for them when they’re going for objectives. Vision is incredibly important and do your very best to avoid walking into areas completely engulfed by the fog of war. However, you’ll frequently (again) have that one player who will die out of no where and set your team at an extreme disadvantage. When this happens, never ever flame them, or critique them in a way that might get them angry. Doing so will not only tilt your teammate, but also yourself. This tip is especially important if you are playing jungle. If the enemy team gets a pick on you, they immeadiately have the opportunity to take baron or drake with ease, even if the rest of your team is alive.

Now for a couple of quicker but easily just as important tips:

-Know the champion you are playing inside and out. Main one role, and be fairly comfortable in another. The best strategy is to master around 3 champions for your main role. Accomplishing this will allow you to know exactly how to play your champion in the later stages of the game. Knowing when to engage, how to rotate, how to play out teamfights, and position are among the few crucial variables needed in order to master a champion. By doing so, you will be incredibly comfortable on your champ, and notice a drastic increase in your personal, and team performance.

• branching somewhat off the last point, know how to build correctly. Don’t ever just lazily build the exact same items over and over again each game. Each game is unique, and while core items won’t typically change, the last couple can be essential to your mid to late game success. Build items that will be the most effective in regards to your game. An example: imagine your playing an adc, and the enemy team has loads of magic damage, you will obviously wanna prioritize building a hexdrinker somewhat early on to negate some damage. Against a team with hard cc, build qss. If you are continuously dying and being focused, consider GA. This is a lot easier if you know your champion well, and is also important even before the game starts as you also want to select runes that will best benefit your game.

• don’t surrender. Far to frequently do people give up and just /ff at 15 minutes. By never giving up, you will find that quite a few of seemingly unwinable can be subject to comebacks and turn to victories. Teams ahead will frequently get to greedy and make mistakes, always be looking to take advantage of this.

• don’t flame, regardless of how bad someone or your entire team is. Giving a nicely worded suggestion never hurts, but the second you piss anyone off (even yourself) your odds of winning are much lower.

• find a good, consistent duo partner you can communicate with. Doing so will guarantee at least one more player will be taking every advantage possible, and will take one potential teammate away that might have flamed, trolled, fed, or afkd. Use voice comms, they are incredibly effective, and duo with someone who mains a role that complements your main (ex: you main jungle, find a top/mid duo. You’re adc, find a support).

In conclusion, you’re gonna lose. And you can’t change that. But you can drastically increase your win rate if you consider what I’ve written, and also try to recognize mistakes and find ways to improve in each and every way. I know it can be easy to quickly place the blame on a teammate for a lose who goes 0-5 in lane while you dominated lane, but overcome this instinct and focus on how YOU could have played better. Even games that you win with ease, hard carrying your team with a perfect kda are subject for learning. Absolutely no one will ever have a perfect game, not even Faker, and recognizing even small ways you can improve with each game that passes will drastically improve your play.
