Thats why it applies grevious wounds, the damage is insane as well, at 50% health it becomes 300/525/750 + 225%, shorter duration means better nukage, his ult is to resemble what Zed's do in DoT where it can't be completly nullified with Zhonia or barrier, I wouldn't completly agree gunblade is good on him, but Sheen to TF would be pretty good for the AP ratio on his heal, where he can sustain in lane or jungle pretty good.
