What about how that death stalker in the woods was basically impervious to bullets as well as the giant never more in the same area
I preface this by saying that once again, I do not want to see any changes, nor do I think that these inconsistencies should be removed from the game.
Now I'm no expert on Grimm [mostly because we're never given specifics as far as I can tell], but I do know about guns. And boy, they do get big. Now, seeing as the Death Stalker was killed with a hit by the grand total of the force of a falling Nora hammer hit combined with effectively two man-personal grenades on what would be a relatively large surface area compared to proper munitions, they do not have that much armor, at least relatively. Maybe the top armor is weaker, but it both doesn't look like it and regardless, should not matter. Compare that to modern day anti-tank weaponry. Big fuck-off heavy rockets designed to penetrate 700mm of composite armor [which would be orders of magnitude stronger than anything nature would likely produce] moving at several times the speed of sound would do the trick. Even an AT-4, which costs like a thousand dollars and is very easily man portable and usable in confined spaces, while not being able to kill a T-90, would liquefy a grimm that can be penetrated by two grenades and a hammer swing.
As for the nevermore, anything that is light enough to fly is light enough to be fucked raw by anything larger than small arms. Unless it is made of some super material that I don't know about. The question then is why are they not bred for their super light super armor and harvested to make protective suits. Maybe that's what the stupid white chestplate is? Fucking conspiracy theory.
I haven't seen the goliaths fight, nor do I have any source on their armor thickness or durability, but the main point is this: the upper limit for man-portable firepower is massive. If a weapon can destroy a modern tank, I find it difficult to believe that it cannot kill an armored elephant. And RWBY takes place in the science fiction future, where heavier-than-air battleships can fly around, and weapons can retract into hammerspace, so the limit on man-portable firepower is likely even larger.
@Kurai's got it right. I'm here to play revolver ocelot a cool magic hunter, fuck logic. But the show makes 0% sense, which I am OK with when I'm in an RP. But, once again, if I wanted logic in my supersoldiers I would go read Uber, which I already do. [fucking series 2 soon, max hype]
But to address your point @Kurai: Grimm are never shown to be numerous enough or dangerous enough to warrant the massive costs and strange prestige associated with the training and operation of huntsmen. Napalm's cheap and bullets are cheaper.
Now, I do see a need for huntsmen to exist to fight other huntsmen. Modern weapons are not designed to kill supersoldiers, but they are really good at killing animals. I can't think of an easy way to eliminate an enemy hunter without another hunter or extraordinary expenditure of materiel. Hunters being soldiers trained to kill other hunters would make way more sense, and would explain why they always train to fight humans rather than grimm [except that one time when Weiss fails to kill a boar, I guess]. Maybe that's the whole twist of the show: Ozpin wants World War 3 and has slowly shifted the curriculum of Beacon and the world to train huntsmen to fight each other in order to get a stiffy at some good ol' Vernichtungsschlacht
