The passive's been pretty difficult to describe in text, I agree, but I don't think it would be complicated at all in practice. Emptylord's image below will help, but the basic idea is that you have this meter that you fill up with your abilities, and the more full it is, the exponentially better the healing (so you're encouraged to fill up the meter completely). There's no real in-game math or counter-intuitive thinking to be done, because the core reward is pretty simple (more blood -> more damage and healing).

While Corrupted Blood has a smaller AoE than Vlad's current E, I think it would be still enough to clear waves, and with his Q being AoE (see below) he would remain a great waveclearing champion. I also deliberately gave its explosion a radius as large as that of his ult so that he could hit every enemy champion affected by his Hemoplague. It would be harder for him overall to damage everyone at once 24/7, but at the same time he'd get massively better rewards against the champions he'd succeed at focusing down, so more difficult plays would benefit him tons more (he could heal from practically 0 to full health with his ult, for example).

I was thinking the Q spike would work more like Yasuo's Q with a travel time, so the spike would travel from Vlad and piece through every enemy in its path. Going into more detail, since it's a spike I also think it should end in a point, so the farther the enemy the harder it would be to hit them, as the projectile would get thinner and take longer to hit.

20% current health is a large cost, but unless there's definite proof to the contrary I think it's worth keeping on Sanguine Pool: it's a massively powerful ability and a huge point of decision-making for Vladimir, so it makes sense that it should have a large cooldown and heavy cost.
