Not unless on a read, J3 reaches very far and very fast and can be done before he even reaches max height, at which point he is +-1/2
can NW do 48% with his combos? thats the damage joker does with J2 and he can get up to 29% meterless/35% 1 bar off of a J3 on hit
J3 is an awesome aspect of joker because it has great advantage, its like a ridiculously awesome JIP.
By vortex I mean this setup, its nearly 100% a guess if the sweep is done at lowest height and sometimes not even the joker player will know which side hes gonna end up in.

Both have answers to each other but i dont feel NW has something that straight up breaks the fundamentals of jokers gameplan, especially since joker loves low mobility in his zoners and a sub par aerial game compared to J3
