Cho player here.
His Q has a very high mana cost and is easy to dodge.
He's also very weak early game and NEEDS to get that CS and kill participation before he builds up to that 5k HP monster that can abuse Stoneplate to do 1k+ true damage on his ult.
Even with that Stoneplate cheese, he's still pretty easy to kite and avoid if he runs after you. I find I have a hard time getting to the enemy squishies and I usually just try zone them to where I want to go as if they're "AAHHH GET AWAY FROM CHO BEFORE HE EATS YOU!" They'll be less likely to notice my ADC and support sneaking around to flank them. Or to just sit on top my squishies to tank the skillshots and prevent the enemy from trying to dive in.
Yeah go ahead buddy. Try and get to Jinx. See if you can get past the giant void monster.
