Game Mechanics: Plane Mobs drop chances

[Skope]

I think it's the chance of drops that's slightly low in general (with the exception of gear which seems to drop at a normal rate). I haven't seen words dropping in a very long time, and gems seem to drop at a somewhat low rate.

He is right about the ghouls though, which there does seem to be a lack of even if you consider that there weren't many ghouls to begin with.
