I found the comment on trash drops interesting. Not sure what is wrong with that - I find it more "natural" if a beast drops anything but money or a weapon. And what can one do with a paw, or some fur?
I always thought it odd, even more the reasoning that a spider probably ate an adventurer carrying money or an axe. Same goes for the foes one battles, they have tons of armor or weapons, yet one can not pick up anything. At least a (trashy) weapon is sort of "realistic". One can't use it? Well, then you sell it if you can, no?
