They should make it stack-up faster but make it so that on death he loses one-third of the stacks. Add a fancy animation of souls escaping to sell it.

Alternatively, removed the AD Steroid on his ultimate. I'm all for him having one ability that allows him to build full-tank and still do damage at all stages of the game - a lot of tanks have that. However, getting 0-300 bonus AD for free is pushing it. It means he has insane AD/lifestealing potential even while Q is on cooldown.
