[Xenephex]

From my memory, yes - the ratio of quality hides is significantly higher; and the rate of silk drops (at least spiderling) is significantly lower.

But... all of those things changed a lot and changed numerous times over the years. I'm not sure what the devs could possibly have to go on that would make the drop rates for everything just like they were during classic, so I've just decided to live with what they are.
