Well poop, I was hoping for 12. We seemed to get 2 per tier, but then at captain that pattern stopped. I guess it's more like the show this way, as none had 13 main bridge officers. But still, it seems like those giant bridges will still have some positions available for more crew.
Well the biggest problem I have with it is that when you get the big ships (and thus the big bridges) you can't suppliment the prop NPCs with your bridge officers. Really cuts off the immersion when you focus on a single race, or a type of uniform.. and Mr. Science Officer in the standard uniform of the time is over in the back looking busy. This will especially be a problem when they let us have whole ship interiors.. though I'm hoping we'll be able to customize those props by then.
