I’m a fan of ‘Executrix’ myself, but I imagine it only takes one Rotbrain to go “She don’t do tricks!” for it to fall out of favour…
^ This is reflected a lot in Warsong and Burning Blade culture as it’s presented in WoD. Burning Blade expressly forbid chest armour partly to compensate for the heavy banner, and partly because exposing one’s chest is deemed ‘valourous.’ Most big-name Warsong we see forsake chest armour of any kind as well, though that may be just to show off their sick tattoos.
I imagine too it’s partly due to demand; only the Blackrock Clan knew how to shape their namesake ore, and True Iron (as well as Truesteel) isn’t nearly as plentiful. It could be guessed that it was put to more useful things (like an axe anyone could pick up once you’re dead), but that’s purely head-canon.
And the general consensus of the thread is right: shooting or slashing at a stationary or distracted Orc is one thing. Standing down a 7’ monster of a man is horrific under any circumstance, particularly if you were conscripted (as seems to be the case by BFA and was surely partly a case during the 1st-2nd Wars) from tilling Pa’s field two days ago.
