Can we talk about how Runic Echoes actually hurts an AP jungler's ability to duel?

So, in my first game with Runic Echoes as Elise and I get one proc against an enemy Diana who then just blows me up. In the past, with Runeglaive, I could have woven those Sheen procs into more total damage in the course of that skirmish... nope, one proc and then this item is basically useless save for a little bit of AP and movespeed that does nothing to help me kill someone. I never thought I'd say this, but I want Runeglaive back!
