As someone who mains her, yeah. Juri can be a lot of fun to play, but you have to be technically perfect to get most of your wins. She is extremely technical and losing governing momentum of the fight can easily spell out a loss even from a health advantage. Her tools are great at blowing up scrubs though. The easier you can get into the opponents head and read/predict them, the better.
Her fireballs are good, but you need to know when not to use them. You cannot fight a fireball war against Guile, Rose, Poison, post patch Ultra Ryu, Dhalsim, and occasionally Gouken. Ryu used to not be a problem, but that buff for his fierce hadoken is a massive pain in the ass now. Also learn when to discretely ditch your fuhajin stores during blockstun and such so you can regain the ability to throw tech. You can’t throw tech when holding light or medium, and people will take advantage of that if they know you are holding one.
DO NOT, use her divekick as a way to get in. It is extremely unsafe on block. Don’t play the jump back run away game unless you have meter. If they try to chase you down you can EX dive kick. She cant normal divekick out of an away jump after Arcade Edition. Basically don’t be AiAi. That display was fucking embarrassing.
Don’t use your pinwheel as a go to punishing move. You should try to confirm into it with normals. Don’t rely too heavily on the EX version either. It’s is fireball invincible, and ignores hits and normal grabs until the first active frame, but it pulls in the opponent on hit and block. IF they block it, not only does it pull them to you giving them an easier punish, but they also have forever to do it.
NEVER use Ultra 2 as an anti-air. The only time it can work is against Makoto’s ultra 2, and you have to do it immediately after their cinematic.
Use the counter sparingly, it is not as useful as Dudley’s.
You should almost never use super unless it will close a game. Neutral medium kick is your best friend against grapplers. You can use it anti-air depending on the character, but your go-to should be crouching strong. Handle sharp jump ins with crouch fierce, it goes almost completely vertical.
I started learning an entire repertoire of different characters after a certain point to cover for bad match ups, and learn different approaches to the game. Maining Juri, I sub Ken, Gouken, Abel, Seth, Yang, and Hugo.
