“Runa Recomendada: Conquistador.
Leblanc no início tentará te burstar com W e AA para procar o Eletrocutar. Por isso evite levar dano ou tente retaliar da mesma forma caso ela faça isso. Caso ela errar o W, agressive com EW+AA+QE, caso ela tenha te acertado com corrente, não gaste seu Q e espere o efeito para poder usar Q para poder pular com E na adaga e garantir o dano. Use seu W para desviar das correntes com mais facilidades ou usando Shunpo. Feita a Hextech Gunblade ou estando level 6, seu combo vai tirar muito mais dano do que o dela e nada vai te parar. Caso ela consiga ficar forte na partida, compre Zhonya ou itens de resistência mágica que o jogo voltará pra você, não pare de dar roaming para que assim ela seja forçada a te seguir, e devido Katarina ser melhor nas lutas ela não vai se dar muito bem se tentar te focar. Em teamfights, foque assim que houver oportunidade, pois Leblanc dará muito dano no seu time, principalmente no suporte ou no ADC, é importante que seja eliminada das lutas o mais breve possível. O potencial de perigo de Leblanc é de igual para igual visto que Leblanc possui muito dano base com suas correntes e possui facilidade em pick-off e pode ficar forte desta maneira, se tornando um problema devido também possuir muita mobilidade e dano.”
“Incredibly annoying but not that bad to lane against. Don't go for E's on them, they will dodge it then chain you. Look for hooks but don't let them combo you because it will do a ton of damage. Save E for their chain, they can W out of your hook slow so don't try to Q->E.”
“Start Doran + 2 Pots if 1) You think you can outplay her and hit your W's to generate a kill at levels 3-5 or 2) You think she will burst you down post 6 (get an extra ring).
Start Corrupting if you think you will not hit your W's (or you will get poked down) and you rely more on wave clear/spammy poke (you will be way more squisher but more durable -- this is recommended if you are sure you will not get hit by CC spells and instantly die).
I honestly consider the LB matchup a fairly easy one because Taliyah E counters her heavily. The first thing you have to keep in mind against a LB is that her W can be predicted, baited and dodged. If you find yourself near the enemy LeBlanc you will certainly expect a W coming from her, so use E to damage at least 25-40% of her hp and Q for the rest. You can easily setup baits and win the lane by making her dash through your E. Every time you see her using W you should also expect an E so sidestep immediately after the W and try to repeat this process in the other direction for the next combos.
If you struggle against LB go for Cleanse/Barrier but I usually go for Ignite, Time Warp Tonic, Dematerializer and 2 Doran Rings. I usually don't buy MR because I tend to get a kill on LB before I need it. After she's 6 you have to bait her ult in order to fight her and win. On Roams always assume she will follow and always assume she has ult (and your team should be aware of that too, ping them!).
You can try to break her double chain combo by using W properly when she W's towards you.”
“Your goal: Play passive, get hexdrinker if necessary and outscale her.
Leblanc can be obnoxious to play against due to her mobility and burst. At the early stages, you can pressure her quite a bit with your gatling gun. Just make sure that you TRADE BACK. After she uses her combo's, she won't have anything up for a bit, so trade back and keep your HP levels even so she doesn't bully you out of lane.
Her chains can be blocked by minions, or even sidestepped if you're good at reading the opponent. ”
“Against a good leblanc, this matchup is autolose for us(in the laning phase). Stay as far back as you can, and farm safe with Q. She is so good at setting up ganks for junglers, so if you ever get hit by her chain, you are dead. Rush mercs, and from level 6 you want to get your other laners ahead so they can carry you.”
“She will outrade you from lvl 3. The way you counter leblanc is by shoving her into turret. Leblanc has to max W. Basically it's her main damage and waveclear ability, and if you shove her into tower, she can't use it to harrass you. Be careful of ganks because she's really good at setting them up with chains. You can take cleanse or barrier here. You can use time warp tonic and corrupting potion for a stronger early game. Farm for your first hex core and then just focus on pushing her in over and over. You have one of wave clearing abilities in the game, so she won't be able to match that.”
“Leblanc is crippled by her linear engage with W. You outpoke Leblanc very easily if she cant get her full combo on you. Play this like any mid range mage were you can Q her out of lane. If she tries to engage with w have charm ready, she can also sit behind minions and try to auto with W. At level 6 you should watch for her all in and you look to outplay with your mobility against hers. You push lanes VERY fast so you can push her in and roam if you want. You win both in and out of lane as a better assassin. ”
“Leblanc is considered a good match up for Lux because of W being countered by Lux Q.
However, everyone seems to forget that if she just max range bursts you it doesn't really matter.
Not an enjoyable match up, if you're unable to get an early lead then she'll just W spam diagonally to avoid linear skills like your Q.
Do not use Q first ever in this match up.
“Leblanc is big problem for a lot of midlaners, due to her high mobility and harass/assasination potential. Though, if you build Negatron here after Dark Seal, you should be able to win even face to face trades, because once when she jumps on you, she has to stay at least for few seconds to deal her damage, leaving her wide open to your full-burst combo, which will mostly deal more damage than her. Except for that she has hard time to deal with poke, if she doesn't all-in you.”
“The key to winning this matchup is to TRADE BACK. Once she uses her combo, she's useless until it's back up, so you want to make sure you trade back in order to keep the lane even. Mercury treads are good into Leblanc. Her weakness is being shoved in, as she will be forced to use her abilities on the minion wave instead of you. She's good at setting up ganks, so before shoving her in, get some good vision around the lane, and track the enemy jungler. ”
