12 feet in height + the weight is actually correct overall. Because a 12 feet thing made out of pure steel, metal, iron or whatever these mechs are made out of, are pretty light, so add the weapons and drones and stuff then boom. Also the modules have to be LIGHTER, because modules sounds like something that are extremely small, but its mech world, so yea probably a head-sized modules.
Weight and height would make sense if mythical, wouldn’t if parts are below legendary.
Also 12 feet is this tall
