It is punishing because it is % MAX hp so the more you hp you get the more it costs and spellvamp is gone so you have to rely on just the healing in Vlad's kit and maybe Hextech Gunblade (if you somehow justify putting it in your build), so as the cost grows you'll need more time to recover that hp.

Aatrox, Dr. Mundo and Zac and are the only other champions with % hp costs but for Aatrox and Zac it is % current hp instead of max - so the cost gets (much) smaller the lower their current hp gets, Mundo pays % max hp only for his ult but he gets it back several times over the duration.

Also the passive gives less hp when you build AP - it is 140% or 1.4 now so for 100AP you get 140hp, and the new version is 1.0 so 100AP gets you 100hp. What is increased is the AP he gets from bonus hp - from 2.5% to 4%.
