The Finesse of Mech Templates
Designing a good mech template was not as easy as it sounded.
Technically speaking, even a Novice Mech Designer could convert a mech design into a mech template.
However, it took great expertise in materials science, broad understanding of the material usage in every major region of human space and a large amount of experience in mech design in general to develop a good template.
A bad one could easily be overly specific to the point where not everyone was able to find the right substitution materials.
Perhaps no viable alternative existed.
Perhaps the ones available in a region may be unaffordable.
Perhaps a close substitution material just happened to possess a deviating property that caused the mech to behave much differently than what the ideal design dictated.
Other problems occurred when a mech template became overly broad.
