How to survive against LeBlanc while still able...

Since lately I've seen quite a lot of Leblancs in game.
One of the worst mid opponents I believe.
If I step a little too close to her,I'm forced to recall if u know what I mean.
This makes farming a bit too hard and getting mr against her decreases my damage potential.
Good Leblancs really makes me nuts.
Most of the time I just tower hug,but I really dont like to turtle under the tower.

Any concrete suggestions? >.<"

MR runes, Abyssal Scepter, Rylai's Crystal Scepter

Galio, Sion, Morgana, anyone else that can easily and safely push the wave up to her tower. Leblanc can't push at all without wasting her ultimate and is terrible at last hitting under her tower. She's pretty bad late game as long as she doesn't get too many kills early.

Play Pantheon, Talon, Kassadin, Akali and beat the **** out of her. Pretty much anyone with a gap closer or hard CC will wreck a LeBlanc. You can't let a LeBlanc engage first. If you know you can survive her burst be a man and tank it. After shes thrown out all her spells a LeBlanc is pretty helpless.

If you're speaking from Ahri's standpoint of view, my advice would be to farm and harass smartly, get some decent AP items, and go gank by level 6.

Good LeBlancs will negate your ability to do well early game. Going head on with LeBlanc as Ahri early game is like asking for trouble. LB's transition to late game is very bad if she doesn't get fed early game, she's actually much worse compared to Ahri when it comes to dependence on game phase.

I've outlaned and outzoned some LBs occasionally during early games, but this is more of a pure luck or a result of careless gameplays by some LB players. If you know the LB is rather passive in nature, try landing a Charm and combo her. Make her waste that 1 min passive of hers. But otherwise, I'd really recommend you to just play safe and get your revenge late game.
IMHO, LB is the most vulnerable after her Sigil of Silence is on cooldown, because I've hardly seen any LBs who land Distortion without landing Sigil of Silence beforehand. If she wastes her Q, you should go in and land a couple of auto attacks, especially during level 1. You'd be surprise how low her HP is because even a basic attack from any AP squishies chips off a good deal of health from her.

Good LBs will just snowball you real hard early game and you don't want her to be doing that to the rest of the team late game.

Either go for MR glyphs, or else you need a pusher.

Push hard to her turret... she can't farm for **** at her turret. Try running Mordekaiser with a Shen in the jungle. Mord is one of the best farmers in the game, so that should solve both your problems.

Take an AP Yi against her.

Push the lane like a boss, use Meditate instead of having to recall after every time she unloads her combo on you.

Once you have the lane stuck under her turret you can /laugh and go pretend to gank a lane or clear some jungle.

I had a sad day with Ahri yesterday under the foot of LeBlanc! But as soon as team fights hit, I got my revenge >=)

In other words, this is a true statement. Only thing I would add is that her ult is a stronger duplicate of the last spell she used. So she basically has 2 Q's. Be careful =O

Of course that if she's smart she'll have her silence for this

I wouldn't advocate using meditate while standing in the open where she can harass you.

If she lands a wombo combo on you, step back to safety and then meditate.

Only pop it in the middle of her combo if you are getting absolutely destroyed and will die without retreating. The built in mres/armor boost will still count for at least one spell unless she is literally the fastest clicker this side of the Marianna trench.
