Not a direct answer, but can help. Just chill on Champ V and barely anyone attacks you at all. EZ weekly skystones/mystics and less stress to fight over points.

? just reset her, cleave or use fcc with aurius or something. shes not that hard to deal with in arena. unless you have units with copium gears. go back to farming

I guess you could run a first speed Kise and she will usually ult hwayeong, but they could run a squishy fire unit to bait out the Kise ult

You don't because that's their job. A WSchuri is going to oneshot something on your defense all the same and like you said, it's human vs AI. That Hwayoung isn't going to be forced to attack your green bait and whatever you do set up to counter Hwa can be baited anyway.

I bet you see that hwa is always getting buffed though. Wouldn't it be nice to use a hero on defense that deters non-attack skills? Gee...

Trying to contain everything on a defense is actually impossible and will never be possible because it shouldn't be.

10% is also way too low to coast in Champ.

Just have G O D Gear. Easy right? LOL. Trash PVP forever.
