Heres something thats been bouncing around in my head a while now. Leave scrolls where they are but implement something to enhance the system.
For example, scribes could create Legendary scroll binders similar to the existing binders.
So you create say a 'Scroll Binder of Legendary Wrestling' and requires for arguments sake 10x 120 scrolls of any kind, once complete the Binder becomes the 120 Wrestle scroll.
It may devalue some of the higher end scrolls initially but I am sure it would increase the value of 80% of the scrolls that just arent used/stored/discarded.
Potentially the market could get saturated initially due to the amount of useless 120 scrolls people have in storage but they would be soaked up quickly.
Power Scrolls remain in Fel, PvPers are happy. Desirable Power Scrolls are more readily available, PvMers are happy.
PvMers might even be more keen to venture into fel knowing that at some point they may be able to bind up the PS they want.
Just a thought..
As an afterthought, it would require some thought as you can milk 120 imbuing scrolls like there is no tomorrow!!

Maybe limit to certain types, combat/caster etc. Either way, food for thought.
