It's probably because Ted already had some strong stories recently that showcased him at his best, and he went out with in huge, heroic style, defiant to the last against Max Lord. The Question, on the other hand, mysteriously just started contacting Renee, made her his sidekick, investigated Intergang a bit, revealed he had cancer, and then died in the middle of nowhere not too long after.
Plus, Jaime's a totally different kind of Blue Beetle from Ted, mixing in some Spider-Man-esque likability and fun with the overarching mystery of where his powers come from. It seems like they just tried to make Montoya a female Vic. She has nothing special or unique beyond some fantastic characterization in Gotham Central. She's just a woman whom Vic taught to think just about the same as he did, and now she's doing the same things he would've done in the same ways he would've done them (only with less martial arts, probably). It was a bland character transition right when it looked like Vic himself might be getting some of the spotlight he's so sorely lacked. I know I, for one, saw what Rucka was doing with Montoya but thought, "Nah, he's not gonna kill Vic. Vic's got too much going for him right now. He's so much more interesting than Montoya." Oops.
My problem with the Question is the same I had with the Atom. The new Atom is basically an Asian, pre-angst Ray Palmer. Montoya as the Question is basically just a female Vic. What's the point of the change if the character doesn't really change? Plus, Montoya was an interesting character in her own right, so now it feels like they basically destroyed
two characters by stuffing them into the same superhero identity.
