Not major nerf, however I do think she is overtuned
Around this time last year she was also the most picked hero in the entire game. She was only de-throned when Bap received massive buffs making him OP in the process
She is now back to #1
The reason I think Bap was made OP in the first place is because the devs were trying to allow him to compete with Ana. Which simply made him OP.
