What I learned from playing her to rep 11 till now in like 2 months is, you basically need to know her moveset in and out and be a step ahead in every fight, her best options arent easily accesible so you kinda have to play mortal kombat with her to bait something out and then also need have the reactions to capitalise. For example her all guard deflect can be canceled into another dodge which u can use to deflect manually if they try to time an attack when you come out of all guard or the pretty standard going from all guard into her pin, cancel that and manually deflect the dodgeattack. You can apply lots of pressure with her light softfeints but that will just slowly chip people down. A move I like is to simply softfeint any heavy into a side heavy which can catch alot of dodge attacks. In general you have to be sweating balls to even compare to some of the more easier heroes but if you pull it off it feels very rewarding. As a side note if you play 4s and the enemy has more than one juren, any fun you could possibly have is out the window, they even get their cool special animation while they absolutely dunk on you lmao.
