That was my biggest issue with his previous work. I can't help but feel he'll get too invested in the uber sci-fi conceptual stuff and make stuff lose meaning. But in all fairness, like HOX this is a lot of exposition as set up for the new era he's pushing. So while I wasn't blown away by this issue I'm willing to give the series some breathing room to develop the main ideas that'll be explored down the line.
And I'm gonna be saying this a lot, but mutants being born to serve an alien empire for war sounds a good bit like another superpowered human subspecies I know
