It’s a fact that the majority of League of Legends players are in what could be considered to be low ELO, namely, Bronze, Silver and Gold. At this level, players think that they know how to play, often blaming the infamous ELO Hell for their low rank. This line of thinking relies on the idea that your teammates are somehow dragging you down. While that can sometimes be the case, your hidden matchmaking rating or MMR makes it so that you are matched with and against the players who are seen to be of similar skill to you by the system. This makes it so that you’re just as bad as your teammates and opponents. If you don’t believe that you are bad, just look at what a Diamond or high Platinum player could do against your Bronze and Silver opponents, hard-carrying games and THEN say that you are as good as you think. Chances are, you aren’t. It’s just human nature to overestimate your own abilities.
Aside from the basic mechanical skills like orb-walking, last hitting, elementary trading and basic wave control techniques, the most important thing you need to understand to get out of low elo is actually teamfighting. In Bronze, Silver and Gold, the most common thing concerning teamfighting written in chat is “focus adc, noobs, gg”. When someone writes a similar message, he shows that he belongs in the ELO he’s at. Yes, the AD Carry is a priority target, however, he’s not the one who should be focused in most cases, depending on by whom and how the teamfight was started. If, for example, enemy Nocturne went for your AD Carry with his Ultimate while enemy Zed came in from the flank to kill your Mid Laner and you try to Focus their AD Carry… you are an idiot. Even if you manage to kill him, the fight will still be lost because you will die soon after to the enemy Nocturne, Zed, and the other two members of the team turning on you. Instead, you could try and protect your carries from the enemies while kiting back to make it harder for the rest of the enemy team to do damage. If you manage to save your teammates, you can look at turning on them with the numerical advantage, even when your AD and Mid are chunked down.
On the other side of the teamfight possibilities, let look at the often found situation where the enemy AD Carry is mispositioning by standing at the or close to the front line of his team. This is where landing some CC and focusing him down before turning on the rest of his team is a good idea. Basically, when the enemy Mid Laner makes a mistake, punish it by focusing him as the priority target he is. Do not dive for an Ahri, trying to get through her team of Ivern Jungle, Nautilus Top, Tristana ADC and Janna Support. You won’t succeed, you will just die and cost your team the fight.
Another nonsensical whine often found in chat at low elo is teammates bemoaning the fact that their team’s AD Carry is focusing Poppy instead of going for a higher priority target when they themselves dove the enemies as four. The truth of the matter is that the AD Carry cannot ignore tanks. The only job an AD Carry really has is to do consistent damage to the enemy team while staying as safe as he possibly can. If that means chipping away at that Maokai, that’s what he should do. If, however, a wild enemy Jinx appears between the enemy Maokai and your Vayne, he should, of course, immediately switch to the Jinx because she’s closer and of higher priority.
Basically, teamfighting is a very fluid concept. It all depends on what champions your team consists of, what champions are on their team, how fed they are, how fed your team is, who engages first and many other things. The most important thing you have to start doing before you can start getting better is to abandon the concept of “focusing” someone. Teamfights aren’t that simple. Sometimes, you have to play tricky, kiting the enemies back, waiting out the CC and other dangerous spells and chipping at their front line before finally starting to focus that priority target. It all depends. The best way to actually see how it should be done is not playing the game, contrary to what people might tell you. It’s actually watching high ELO streamers who main your position, looking at what they’re doing in the game and trying to imitate them. That’s how Yiliang “Doublelift” Peng first got good, you can do it too.
