There are two things you need to do aganist LeBlanc:
- Stay on the edge of her Disortion range, so you can dodge it by simply moving backwards.
- Catch her while she's Disorting towards you. If she uses it to dodge something, she wastes a lot of damage, as such will use it damage you 95% of the time
I'll give you the rundown of all champions that I can think of that will help you with that.
timing Charm can be wonky, but can be used to negate Disortion. You can use ult to reposition basically negating everything that isn't Q or Q-R.
Obvious offender and anti-assassin. Just drop Tibbers on her face and she dies.
Well timed WE or R will neuter LB just as Ahri.
Too tanky for her too kill and silence prevents her from running away.
Trollpole - self explanatory
Is is even necessary to mention THE anti-mage?
Freeze her when she gets in range and shit on her.
Snare prevents her from recasting Disortion or using Mimicked one. Can be wonky, though.
QWER, send my best regards to your shopkeeper.
As mentioned. Get some MR LB is neutered with mere damage and tankiness.
Assuming you are one of those guys. Instant stun followed by a knockup and a shield on top of that. LB might run away, but she won't kill Riven.
Not seen or player Ryze after his rework, but he still has his point'n'click root. Can't fail with that.
Possibly - never played Swain, but I assume his point'n'click damage and tankiness will make it hard for LB to do anything.
My main and favourite pick aganist any LeBlanc. Stun the bitch when she dashes, drop the bass with the Force of Will, then ult her and walk away as gold is transfered to your account.
Wonky, but you can time Anklecut and dodge her Disortion at which point she'll either dash away with Mimic or die.
The Eyeball could work, but you need to save E for until she dashes, else you automatically lose.
Trollpool + outsustain her.
Same as with Ahri, Lux and Syndra.
He can push her to the tower with ease and well timed Death Mark will negate a lot of LB's damage.
Of course most of those champions require some experience or quick fingers.
Regarding myself. Back when LB was pick-or-ban last season I had to either stop playing my waifu Syndra or learn how to play aganist her. Turned out playing aganist LB is easier than people make it out to be.
