I think we're playing with words muddy a bit the thread.

Simple:
Spartan Armor AND/OR centurion/roman armor, yes good - but it wasn't really the point.

But in game, for women I see legs and for the same armor on men I see full padding, why ? Is it sexist ?

Trying to rationalise that with some example where "it's okay to see legs for men too, it doesn't make them any less badass and it's more practical when walking for days as adventurer and bla .." is what, for one, I used as an attempt to make my point.

if you pull that pic with that cleric and the blue dress half naked, that is just another example to convey the point that yep it's possible on men too.

Arguing with an engineer is like wrestling with a pig in the mud. After a bit, you realize the pig enjoys it.
