Mail replaced segmentata? Why?

[Tarbicus]

But, that would only be a lot of work if wire was only for maille purposes, if there was mass production of wire for any other purpose, maille could be easier to do then plates.

Good point.

I know that romans refered to gauls as beeing very tall, a seg made for roman height could leave parts of the body of a new romanized gaul a bit exposed. while maille could easily cover more of the body.

Briefly, an hamata could be done in a one size fits all, while a seg could not.

Not if the segs were made locally from blooms or plate.
