Riot, Corrupting Potion is wack

We don't care about the damage. Take the damage AWAY, we buy it for the SUSTAIN. Because sustain MATTERS EARLY GAME. You've taken away hunter's potion from the jungle, because you hate sustain. You've taken away a lot of Corrupting Potion's sustain because you hate sustain, and wanted it to deal more damage. But now-- you're taking away its damage, too? Is it the next to go? What??
