What's the point of buying Warmog's anymore...

Warmog's Armor Price increased to 2750 from 2500 HP Regen increased to 200% from 0%. Old Passive : REMOVED. New Unique Passive: Grants Warmog's Heart if you have more than 3000 maximum Health. Warmog's Heart restores 3% of your maximum life per second when you haven't taken damage in 8 seconds.

WTF Riot? What is the reason for these changes to Warmog's. Why can't you leave well enough alone?
