Re the Aerospace phenotype, why does their description make me think
Its one thing that always irked me, they'd not be dinky midgets, their bodies would be less able to endure the g-forces, and at the speeds they're moving at, eyes won't be much use and you'd be working mainly with sensors/radar etc, not the Mk1 eyeball.
If I was to re-do it, i'd make it so that they're 'small' by Clan standards. From what i've read, your Average Warrior is around the 6' tall mark or even taller, they're big, strong people. Not Elementals but still, big gits. You want a smaller pilot, have them be more normal, 5'4 - 5'9 at the most, and with physical training that focuses far more on endurace and cardio-vascular training. So they're not big like a warrior but wiery, with strong hearts and are still strong but wiry in build.
Perhaps fluff it so the original template was Oompa-loompas with O_O eyes but it was rejected by like ALL the Clans, as being too extreme and with far too many costs outweighing the benefits and instead it was re-done as a 'small' but physically fit person instead of the huge diversion with the cannonical aerospace phenotype.
