Are you intentionally ignoring the times he gets grabbed or staggered again because he’s trying for the flawless block?
That’s like saying Liu’s kick string is useless because you can flawless block the last hit. Obviously not.
Likening Jade's kick string to Liu's is like saying that a Cadillac is the same as a Ferrari because both have wheels.
Liu's F4 is arguably the best mid in the game at 9f and beats out every poke in the game either by speed or by range. It leads to a mixup situation with Low Fireball, a launch into MASSIVE damage and a parry into similarly huge damage Jade players can only dream of.
B3 is indeed Jade's best mid at 11f but she has no compelling pressure off of it and the stagger game is highly overshadowed by the fact that she has no decent special to cancel it into. Remember when EX Glaive got blown up every single time? There we go.
I understand that Waz makes her look more powerful than she really is.
I also understand that this website has this nerf-paranoia where everyone wants their main to be buffed, even if it's Erron, and then no other character to receive any fixes because Heavens Forbid someone's character might be stronger than theirs.
But let's be reasonable here. Waz is amazing with Jade. Jade is not as bad as D'Vorah, Frost, or the Kahns. But she does need a proper punish, preferably a way to launch reliably for some decent damage, and a special that makes her B3 game - her only decent mid into any decent scenario - just a bit better.
Not saying make b3 9f though that would be amazing.
Nobody wants Jade to become Brokentier, but you clearly don't understand the character's problems and you aren't willing to listen.
