It's not "disdainful to the mythos". It was just a rad rule of cool type idea that felt right for the genre tone and setting. Like mixing nutella, marshmellow fluff, and peanut butter for a sandwich.

Also I don't know if it's because it's like 3 AM where I'm at. But I'd really like to know you're reasons as to why this tech hierarchy with the mechs is that important for your guys. Because honestly this focusing on statistics would be more appropriate to like tabletop game. Plus it's not like in the mech anime this stuff is ever actually relevant outside of like stuff being posted on the back of the toys or like little factoids in supplementary material for fans.
