What if Nocturne's E 'Unspeakable Horror' Reduced the Targets Armor? @Riot

I've been thinking of ways to add a little bit of power to within a certain means and came up with this idea. Currently Nocturne's E 'unspeakable horror' doesn't seem as rewarding as it should be. Currently it take 2 seconds to plant nightmares into a targets mind before they get feared. Once they are feared it is nice but it's not always a reliable form of cc. It's harder to do then back in 2011/2012 because of the amount of mobility in the game now. To make this spell more rewarding what if the ticks of damage from the spell also reduced the targets armor for a certain % of flat amount per level put into the spell? Or if Nocturne successfully got the fear off then he would be rewarded by literally scaring the armor off of his target. Just a quick thought let me know what you think!
