I say that about Roy because I think becoming Arsenal basically saved Speedy from total irrelevance, and even at that he’s never carried his own book (like Connor Hawke has done). I don’t read Titans titles so I can’t say what’s the latest, but just browsing the racks, Roy is perpetually just a face in the crowd.
And I say that about Cassie because while Donna’s continuity is a mess, she is a fine WG and the addition of Cassie to the mythos adds nothing for me. I’ll pick up more Yara Flor before I’ll buy a book because Cassie is in it.
