I thought that too!
And it could be another way to show Hux is losing his influence within the First Order. Clearly he is not as important as he was in the previous films, and if his army is becoming less important, then we have a more tangible reason why Pryde’s political influence is outgrowing Hux’s.
RogueLeader,
I am still holding out hope someone will implement this idea. I agree it ties into the prequels and TFA line nicely. It also helps explain how they had enough manpower to control the fleet. Finally, I believe it helps reinforce the fact that Palpatine is a clone in this film which is quite murky in the theatrical release.
