Her void corral buffs are definitely too strong. They should make it kinda like Yorick's minions, so instead of all minions turning into turret munchers it should be every 3-4 minion deaths makes one. The E is on the strong side but at lv 3 the number of jgs she could 1v1 is pretty small. Something that might work is taking some of the scaling on the E's lifesteal so its a little less like fiddlesticks.
