The basic Affliction “boss rotation” should still be something like UA -> Corruption -> Bane of Agony -> Haunt -> Shadow Bolt. Haunt refreshes your Corruption through Endless Affliction. Nightfall procs Shadow Bolts. When the target is wounded, you can switch to Drain Soul.
On faster fights, you can go Corruption -> Shadow Bolt -> Drain Soul, or even Shadow Bolt / Searing Pain for very fast fights.
When you need to run you can use Fel Flame.
The general DPCT should be something like this (off the top of my head, so this may not be perfect): Drain Soul (wounded), UA, Bane of Agony, Bane of Doom, Corruption, Haunt, Shadow Bolt, Incinerate, Drain Life, Drain Soul (not wounded).
Most of the Drain Life stuff in the talent tree is to support PvP, leveling or when you need health.
This is all work in progress of course, and not etched in stone. (Source)
