How does Zealot's Oath + Eternal Youth work together?

If you take both Zaelot's Oath and Eternal Youth, what is the final result?

Recharge and Regeneration are separate mechanics. Eternal Youth will reduce your life regen and leech, and remove your ES recharge, but will give you life recharge (33.3% of Life Recharged per second). Zealot's Oath will leave you with 0 life regen and half of your original life regen as ES regen.

So end result is?:
- Life does't regenerate.
- Life recharges at ES recharge rate (33,3% per second)
- ES doesn't recharge.
- ES regenerates at 50% of life regeneneration rate (% based on amount of ES)
- Life leech 50% rate

So the thing that protects life is at constant regeneration. And life which is hit less often (due to ES) recharges when you are not hit.

Is this worth it to take? I have consecrated ground when standing still, and could gear for high ES and life regen. Or does this require very specific build to be worth it?
