As of Patch 2.3 Shadow Embrace will no longer count as an Affliction spell for the Siphon Life talent bonus, making the talent pretty damn useless to most Warlocks (there's always someone else who can go full Shadow Embrace for raids, right?).
Since Improved Life Tap isn't that needed with Dark Pact, you can skip those as well. Suppression is nice for dumping points, but later on you'll get enough Spell Hit Rating so you don't have to max it out (I only put one point in it).
I think you'll agree with me that Improved Drain Soul is good for the 10% less threat. As a bonus, it makes farming for shards much easier (use rank 1 Drain Soul). My Warlock has roughly 7500 mana which means that she'll get back a shard and 1125 mana whenever she kills something while draining its soul.
Affliction:
5/5 Improved Corruption
2/2 Soul Siphon
2/2 Improved Drain Soul
As you can see, we now need one more point to unlock the next row of talents. Suppression makes for a great talent here. 2% isn't a lot, but it'll save you some Spell Hit Rating in the run.
1/5 Suppression
1/1 Amplify Curse
5/5 Fel Concentration
2/2 Grim Reach
2/2 Nightfall
3/3 Empowered Corruption
1/1 Siphon Life
1/1 Curse of Exhaustion
5/5 Shadow Mastery
5/5 Contagion
1/1 Dark Pact
Up until now it's been pretty straightforward. As you can see I skipped Shadow Embrace due to the Patch 2.3 change. What you decide to do from here on and out is up to your playstyle. I suggest:
2/2 Howl of Terror
3/3 Malediction
1/1 Unstable Affliction
I don't remember the exact math, but I remember reading that unless you have a ******** of Spell Crit Rating, Unstable Affliction beats Ruin in DPS. Since Spell Crit Rating isn't really useful for an Affliction Warlock (DoTs can't crit *sob*) I put my money on Unstable Affliction.
Note that you only need 2 points in Malediction to unlock Unstable Affliction. I put the last point in there because once I'm done with the other talent trees I'll have one point in spare and Malediction is +3 to the Shadow Priest and Mage epeens out there.
Demonology:
5/5 Demonic Embrace
We'll get back to Demonology later.
Destruction:
5/5 Improved Shadow Bolt
5/5 Bane
1/1 Shadowburn
That's pretty much what I consider MUST HAVE talents for a heavy Affliction build. If you didn't put 3 points in Malediction you'll now have 4 points to dump wherever. I highly recommend maxing out Malediction as you'll gain a couple of new fan clubs if you're the Curse of Shadow ***** in the raid.
This is how I'd put the last 3 points:
Demonology:
3/3 Improved Imp
or
3/3 Fel Intellect
It's a matter of preference, in my opinion. Do you want 3% more mana and a larger mana battery to suck from with Dark Pact, or do you want 30% more health from Blood Pact? With Improved Imp your Blood Pact will be increased from 70 to 90 stamina. That's only 20 stamina (200 health) and I'm debating whether or not there are better talents to spend them on.
Anyway, that's how I'd go with the new changes and everything. I just hope the note about Shadow Embrace is true, otherwise my nice build will go down the drain.
