it s just an idea, but imho it could work. what about making dragontouched armors three slotted armors with one slot for each type of rune - but making those runes freely replacable. ie u can switch freely between runes u have farmed without destroying them in process.
this way u can have good versatile armor which can be situationally strong.
imho it would bring more people to reavers reach and make those armors something more than just piece for one or two levels. just now lot of those are unused and generally unwanted
