You will serve me in The Netherrealm
You don't even need to whiff punish it though. She's -7 after it, so if you block it, it's your turn. 11F mid, low poke into pressure, throw, whatever your character has. It's a safe way for Jacqui to get in, but she gives up her turn. From the range it comes out you're probably already ducking anyways, so it's not like you'd need to worry about the low/OH mixup, you can just block low.
I'm certainly not trying to downplay her, right now she's easily a top 5, probably even top 3 character in the game at the moment, but I don't think she's game-breakingly good. I don't think she's unfair.
She's definitely in the top 5 conversation. I don't think she's busted but She is super annoying.
