The OP doesn't want a boost to those rings. They mentioned more than once that the rings are great for the difficulty involved. The suggestion was a change to put them on par with the others as far as how easy they are to trivialize with respect to the worn effect.
Really I don't know how such a request could possibly be satisfied without creating a situation which would less satisfactory. There are two ways you could do this: add a rare focus effect to the item, or add an effect that is cumulative. If you give this ring a focus effect that is hard to replace people will use the item longer because they will be "locked-in" to wearing this item since they can't replace the focus effect (a situation most casters are familiar with). Adding flowing thought would probably get people to wear it longer, but ft is equivalent to just adding raw mana (because nobody using this ring will have max ft). Adding -aggression wouldn't work well either because it's not useful for healers, necros, or enchanters (wouldn't make people use keep using this ring) and for wizards and magicians it's quite useful and not easily replaced (lock-in again).
