Taylor has done wonders for Nightwing's sales and I hope he can do the same for the Titans, but he will leave no impact on the character because he hasn't written nor created anything worth remembering. It's truly impressive.
No, I definitely don't want to see her in the Titans book. There is no need for her to show up, especially when they have Cyborg on the team. They need to figure out something for her because having her around all the time does nothing for Dick either. He ends up doing less on his own and that's no fun as a reader but to be fair I have dropped the book a while ago, maybe things have changed, but I doubt it.
