Why the Secret Spell Scroll system would have never worked.

Easy fix for duping: make it so trading, buying from permits/mushies, and dropping are all save points.

Yup, and I have been wondering this whole time why they don't just do that. I guess they're worried about it being used for DoS attacks, although that already happens anyway so who cares that there'd be another way? At least people could no longer dupe when the servers were crashed.
