Will have to see more from her, but from a passionate fan pov I know I'm gonna find it difficult to feel ok with the change. I personally feel that way with some vocals, some are just unreplaceable, you see? In the case of Chester you know that he imprinted so much of his personality in the songs.
It's like GNR without Axl or Queen without Freddie. It will inevitably feel off in the beginning and she'll have to prove herself worthy of the massive fanbase. Can they make hits? I wouldn't want to be in her shoes lmao lots of pressure there
