Ghost Reaver / Life leech / Energy Leech Question

Okay, so I've been reading some stuff around about the energy shield leech.I have the Ghost reaver passive node. according to other players.
Any modifiers to life leech will not apply to energy shield leech except for
"x% Attack damage leeched as life* . that is the only thing that works with ghost reaver.

Vaal pact does not work with Ghost reaver because Vaal pact modifiers are only for life leech for example "maximum total recovery per second from life leech is doubled" so basically any modifiers that refers only to life leech will not work with ghost reaver?

for example for daggers, the passive node :
-Dagger damage and leech (beside Stabbing Thirst passive node)
it says there *20% increased total recovery per second from life leech"

or another example for claws, :
-SOUL RAKER passive node
(50% increased total Recovery per second from life leech"

Sooooo, if Vaal pact does not work on ghost reaver because it only refers to life leech. Does Soul Raker and other passives that refer to life leech will not Work too?

can someone confirm?

"Recover speed from leech" isn't "leech". Pretty simple really.

it says life leech not energy leech. coz if its that simple then why vaal pact does not work?

vaal pact increases speed leech if im gonna apply what you just said. then why does it not work?

they just added a couple of new mods a couple patch ago.
check notable passives Ethereal feast / light eater.
