The item is too strong but would rather an enemy that can hit you 3 times before you even get to them abuse it or melee's have an item that isn't nerfed to crap because of what another class did. Yes riven and fiora are stronger now because an item they built anyway is better now but ranged champions abuse it much more than they do, they need the 15% DOT to survive, their melee, a ranged champion that has that and a Phantom Dancer, and that's what draven get's, should be as tanky as they get with those 2 items.
Ranged champions have a long history of abusing item's, Sterkas, Maw, All lethality items, Black Clever, all of them were abused my ranged champions but needed by melee's and all of them got nerfed because of it.
