Lingering Apparition's tooltip is corrected for next build -- its functionality in this build is the intended one. It reduces e the cooldown of Wraith Walk by 15 seconds and increases its movement speed by 30% (to 100%). The duration change to 3 seconds affects all specs.
It's also worth mentioning that the animation for Wraith Walk is, um, very placeholder.
With regards to AE, Unholy should be at its strongest when there are multiple targets present for an extended period of time, especially if they are clumped up. We need to do some work on the spread of damage contribution -- almost everything needs to come up a little bit, especially the abilities that give the spec "rot" damage (Festering Strike/Scourge Strike are unlikely go up by much). We don't plan to change Death & Decay's baseline uptime right now - using it skilfully is a good opportunity for Unholy players to shine in short AE windows. Epidemic should offer an additional way to deal damage in a very prolonged AE situation, and is especially good against swarms of enemies.
