Like you can say Batman did better in the rematch a few issues later? But.... honestly didn't really do all that better in the rematch a few issues later, as she was fighting him and Cassandra at the same time (and several other members of the Bat family, though Azrael and Batwing and Batwoman were at least wounded and explicitly suffering from blood loss before the fight started, and only helped initially), and at one point Cassandra straight up blocked a sword strike from Shiva that would have otherwise shanked/killed him, and she pretty clearly did the heavy lifting in that fight of the two of them. He at least managed to block a couple shots this time and also hit her when her back was turned and her daughter had her attention in a conversation.
But hey, he managed to block her twice! Annd was still going to die at one point. And other people were fighting her. So.. yeah. It didn't really salvage much.
So it really comes down to what all else Shiva has managed to do since that whole mini arc. Which is to say, does anyone know of any showings from her since that whole mini arc? Yes yes, she theoretically died at the end. I doubt it stuck.
Though if she actually has stayed dead since then, ugh. (And I mean there's that she died to Ra's Al Ghul shooting her from behind? Buuut that only happened after Cassandra kicked the crap out of her).
