Energy Leech support gives no leech

Regardless of the damage I do with Arc + Unleash, the energy shield leech support isn't moving my ES at all. I can only see the life leech making an impact on my 3k+ life but nothing happens for my 1k+ ES.

6L: Arc+Energy Shield Leech+Unleash+Ice Bite+Life leech+Added lightning damage.

Also have mastery: 1% of Elemental damage leeched as ES. Also can't see any leech happening at all.


Sorry no SS because I can't take an SS of my ES not leeching.
