At least Bishop is a captain so we have that. I just wish he will get showcased as one soon. We haven't had a clear indication that he is captain outside a data page unless I'm mistaken. I would like to see him in X-force with Jean and Colossus to be honest, but so far he's been used well here but like you I want to see more. I also want to see him in charge and not blindly following anyone. Though a lot of the X-men are following in this new era because ultimately they believe in the new direction.
I hope Bishop has a good role in the upcoming crossover (or at least a good moment). The earlier Marauder issue with Kitty and Bishop has probably been my favorite of the series thus far. Unlike many here I do not dislike Kate (Kitty) but I'm glad she has been paused so others can get some spotlight. The great thing about this new era is that almost all our favs are in a book.
