Sometimes depending on the situation time may force you to Abyssal Drain under not ideal circumstances.

When it comes to bosses, unless they have a lot of small adds I wouldn't even try using Abyssal Drain as you will be better served by constant Dark Arts + Soul Eater combos. Also a tip for when you are fighting bosses, try to time your powered up Soul Eater to land right after a bit hit is going to land or after a tank buster. It helps the healers out tremendously. I know with proper mitigation abilities I can get hits down from 10k or 9k to around 5k if I know it's coming. A good 5 or 6k hit isn't bad when you heal around 2k of it right after it lands.

A good place to practice this is in Hullbreaker Island(Hard) as the mob before the last boss consistently uses a large hit for around 9-10k with proper warning in advance. If you get good enough at timing certain things you may even be able to try and make sure Reprisal will be up to offer a little more cushion.
