I have a damage on block char and it would fit the concept really nicely, so I socketed in 4 skulls and rolled life reg on chest.
I expected some form of life reg, nothing astonishing but atleast something, but not 1 hp every 2 seconds for 5 affixes on a level 30 char. XD
If this is the intended amount of regen, you might as well delete it from the game, before more people brick their items.
Slightly off topic: Regainable health on blue items does work, solace ring does not do anything, not as blue, not as exalted
