When you are deconstructing runes does the level of potency or aspect you can actually use effect your ability to get lucky enough to extract the runes.
(FYI: I bought a VR9-12 Gold rune at a good price, but can't craft VR9-12 or Gold aspect yet. I am trying to decide whether to decon it now or hold on to it till I can craft those levels).
FOOTNOTE: Zenimax please do something about the punishing difficulty of leveling enchanting compared to all other crafting professions.
