Gragas

he can ruin your all in with only E, he has only 5 sec cd if he hits anything with E dont think you can all in him after he uses it on minions, you can try to bait his E with canceling Q with ward jump but its not common

Graves

he scales well in late game and does almost same dmg as lee sin in early, very strong you can try to counter gank or tell your solo laners to help you invade

this champ will always be threat for everyone, perma ban him

Kha'Zix

you can destroy him in early only if he goes 6/1 after he was 0/1 you are ****ed but if your team helps you pretty easy
