Where do you envision the Blade position compared to others Vanduul ships, we know it's a light fighter but is it more of a "Gladius" or closer to a "M50"?

It's a mix of the two, the Blade is lighter armed than the Gladius but makes up for that shortfall by being more agile. A Blade pilot's best strength is to evade incoming fire and stay on its target's tail.
