What's the most overlooked aspect of League of Legends?
The mindset. Everyone talks about what champions are the best to play, advanced strategies, item builds and runes. But little people care to speak about your mindset.
Everyone knows the satisfaction of winning a hard match with a lot of back and forth and maybe even a backdoor. And you also know the opposite side, losing after being ahead all game long. Try to remember how you felt after each situation.
I feel really good after a win, positive, pumped ready to face new enemies and stomp them.
And after the loss I used to feel down, unhappy and frustrated. When looking to climb fast efficiently you really need to clear your mind after a loss otherwise it will negatively affect your gameplay. You want to keep the positive vibes after a win and use this boost of morale to keep on winning.
The key is taking breaks after a loss. You just do something else, grab something to eat/drink, go pee and listen to your favorite tunes. It is very important to shift your mind away from the negativity. Tilting is very common and loses a lot of solo queue games. Everyone knows this guy that starts a surrender vote after a single person get's caught and your still ahead. Some of them are just trolling but others are actually serious. And that's what you especially find in low elo.
You lose focus and waste time by complaining in chat and even by reading it. So if you know that you are the better player and you, therefore, take all the kills and someone complains like "omg why do you ks" or "cmon" and so on just go ahead and mute them. Even if you think you are tilt-proof, subconsciously it is going to affect you. I used to teach people on what they can do in order to improve but people don't want to hear this, they think they are playing perfectly and it's just their team losing their games. Admit failure and don't be stubborn be a nice teammate and only write positive things like "gj" after a successful gank or a nice outplay by one of your laners.
Limit your time spent on typing to a minimum, only give useful information for example "enemy jungler is botside care" and use the pings. Ping that your laners just burned his summoner spells, ping that they just hit level 6 or that they are missing. Sometimes people don't notice a single ping so if you see that your laners don't react ping a couple more times with a back ping without being annoying.
And if you notice that your teammates are ignorant do not bother to use the mute function.
And please play on a smurf account when learning a new role or champions. If you are still looking for a place to buy a lol account that is the best website to buy a lol account.
Write something about yourself. No need to be fancy, just an overview.
