I see it less as it being Angel and more about Writers and Editors not knowing what to do with him besides cashing in on 90's nostalgia. This is why I want to see Angel outside the X-books for a bit while Betsy grows as a character in UXM or any other book she is present in. That way it would serve both characters right. They can explore different avenues without being tied down with relationship drama cashing in on things that no longer appeal.
