sounds pretty interesting. No longer 1/2 of the inventory full of pots
@poechalcho: the old system was a normal health system with pots from the npcs/drops + you have a chance to find fountains which will heal you 100% but are only usable once or twice depending on the size of it.
Diablo III's health system is designed to keep you thinking on your feet and rushing toward the next fight. As a hero struggling against the sinister forces of the Burning Hells, fleeing from battle to recover your strength isn't an option. To avoid dying a gruesome death, you'll need to hunt for ways to keep up your strength.
