Not this "exotic weapon" nonsense again, it's a crap argument, to coverup a bias towards certain gear.
Lets stop kidding ourselves on. C-rpg is a blatantly multicultural mod, a far cry from a pure European era mod.
There's plenty of gear from other cultures, not of European origin, and they don't receive these penalties, So why should Japanese gear be any different?
How about just treating it like any other equipment in the mod, Instead of this prejudice towards Far-eastern equipment. Would be nice to have some equality in C-rpg
