Warlock Talent: Nether Studies rework

[Decemus]

As far as I know, right now the Nether Studies talent in Demonology tree is skipped by everyone except levelers, and it does not look good to have a skippable talent so far down into a talent tree. I propose these changes:
Instead of "Increases the effect of your Succubus' Seduction, your Voidwalker's Torment, your Imp's Blood Pact and your Felhunter's Tainted Blood spells by 15/30/45%".
We would get this: "Increases the effect of your Succubus' Soothing Kiss, your Voidwalker's Torment, your Imp's Blood Pact and your Felhunter's Tainted Blood spells by 15/30/45%. Increases the duration of your control over Greater Demons by 5/10/15%".
This way we trade Seduction for a much more useful Soothing Kiss, and also give max level players a reason to pick this talent.

Please no, demonology as a talent tree is already requiring you to put in more than 31 points to get just the absolute essentials for the spec. Currently thats 34.
With nether studies providing 45seconds longer duration on inferno, its a must pick talent for difficault content.

Its one of the few talents that actually rewards you for playing your regular demons and you can skip if you want to. Allowing for at least some talent point flexibility with the spec.

The soothing kiss thing i'm indifferent about, Its mostly irrelevant considering Deep demos threat is on the Demons, not himself. And he can always summon a new succubus if she has too much threat.
but if nether studies includes greater demons, the talent tree becomes even more of a talent point hog.
