Talon

I always ban this guy because of his parkour skills and infinite damage on all abilities

Zoe

Aspect of the Targon IS a big problem
Boom one shot

Fizz

Every Fizz is annoying, and you know it...

Yasuo

Can easily dodge your E+Q combo and block it with his windwall/dash.
BUT his windwall DOESN'T block your W (do not forget!) - so you can easily bait out his windwall and try to take him down.
It really depends on the player

Zed

If he gets into your "intimate space" you are not happy.
Can dodge your E+Q with his W

Ekko

Ekko is just... annoying.
If he F**** up his play, he wil just ult and kill you

Katarina

Can take you down very easily.
Depends on the player

Viktor

Pain in the ***
Lazer dude will shoot you down immediately, if he has phase rush

Vladimir

He can dodge almost everything with his W.
Do not play aggerssive against this guy

Diana

She can harras you very hard, but if you ask for ganks, she shouldn't be a big problem, unless you let her feed on you

Sylas

Ult stealer.
He really likes to get into your "intimate space" with his E

Kassadin

Ult machine.
Try to play aggressive till he gets 6, then he will be a problem

Azir

Depends on the player.
Try to not get hit by his R and Q

Xerath

If he lands his E, than you are in a big trouble.
Depends on the player

Galio

Well, he has a roam potential like you, and his MR is very annoying.

Qiyana

Try to avoid missing your Q and do not stick to walls as she will ult and end you.

Neeko

This chameleon girl is annoying, trust me

Akali

Do not waste your ult, when she uses her smoke. Just wait till she has low hp and then vomit on her

Irelia

DO NOT attack her when she has her passive stacked

Ahri

Try not to get charmed

Vel'Koz

Not so much to talk about.
Try to avoid getting his passive stacked on you

LeBlanc

Do not play aggressive.
Farm under turret and ask for ganks

Syndra

She just ballin' .
Don't get balled by her as she is very stron against you.
Go feed yourself on bot

Annie

She isn't that much of a problem.
But be careful on Ti🅱🅱ers, because he will just smash the heck out of you

Corki

Weak rat in a helicopter

Twisted Fate

Try to avoid getting hit by his cards

Ziggs

Boomer

Cassiopeia

Orianna

She isn't big problem, but be careful, because she can be really strong

Yone

Another Yasuo, but this one does not have a windwall. Instead of it, he has good escapes. Play passive, no need to die and get him fed
