Both game and myself have addressed this on more than one occasion, no matter what we do there will always only be a few runes that are desirable. Before we added the scrolls i got constant complaints that zod/cham were 100% useless, and people wouldn't even pick them up.

You also have to keep in mind that we added 2 new high runes at the top end (tor and xer) so obviously the ones that were at the low end are no longer considered high runes.
