Warlock steal lifeforce adjustment

[Paragoons]

Can we not adjust Warlock steal lifeforce enhancement skill from Soul Eater tree?
It doesn't do all that well while its a potentially interesting skill , why not make it be 50% of spellpower or 50% dice or you heal on hit or something, it does barely anything especially with that cooldown.

Its not powerful in heroics, its not powerful in epics especially with rejuv cacoon

Make it accept metamagic feats (Maximize, Empower, ...)
Make it benefit from effects that improve the Stricken SLA (Greater Hunger and such)
Decrease cooldown to match Stricken.

The Dark Feeding SLA could also use a facelift.
On the buff side, instead of Insight bonus, the effect could be fully stacking, or at least Profane. Also, it should grant a more useful benefit to be worth casting. Some spell power, maybe extra pact die?
On the debuff side, the SLA needs more. Maybe a neg.level or 1d4.

I mean, a lot of trees have fluff of scrap abilities as priority builds keep using the most optimal ones.

It is basically AP wastage or flavor.

As mentioned above, to make any spell ability viable, you have to either match it to Metamagic use OR make it scale in some manner as you level.
