Zlandi Heart - better for necro or enc?

[commongood]

A friend of mine and I were discussing this. Having played both classes to 60 (enc on live, necro on p99) I definitely feel like the item is very good for either class.

For the necro it just ups effeciency increasing the time between having to worry about your life total when in Demi Lich.

For the enc it has no immediate benefit as long as you are not being beaten on. However you will get beaten on. Especially when charm-soloing and having a charm break causes you to drop to ~20% hp before recovering. This leaves a long recovery time before your hp regen up naturally to an acceptable amount for you to responsibly continue what you were doing. The 5 extra regen is a pretty big boon here too.

What are some of your thoughts?
