Lulu might be, kha just got nerfed, the big thing is you have to outplay him by paying attention to his mechanics, you have to try not to get isolated, so when he is fighting you stay in minions or next to an ally, Elise is very good at this because of spider for guarantees no isolation, and don't lose sight of him. when you start a fight if he gets low drop a pink if he ults and you lose sight of him for a second he gets a refresh on his passive and it actually hurts alot, if you do both of these things you can usually out dual him easily with most champs.
