Remember that Dark Dance has a relatively short cooldown and any hit that is parried still gives full mp back, so it is good to always have that up at the start of a pull regardless. However, make sure you are not using Dark Arts + Dark Dance if you want to get maximum mp back, as it adds evasion with Dark Arts.
In my opinion, depending on how large the pull is, you can lead off with a Shadow Skin + Dark Dance, followed by Dark Arts + Abyssal Drain (Repeat the last combo as magic levels permit) that will generally establish a good threshold of enmity and be pretty self sustaining at the same time.
An alternative to that combo is Dark Arts + Dark Dance (for the parry and 20% evasion) and Dark Arts + Dark Passenger (for the blind and AoE threat) followed by some Dark Arts + Soul Eater Combos to keep your health up. You will need to adjust the combo pattern depending on the relative threat levels of your party members though, so it is not set in stone.
A warning with the second combo though, don’t pop Blood Price if you use Dark Dance and Dark Passenger with Dark Arts, as you will dodge too many hits to make full use of Blood Price. I usually save it for when that wears off and I pop Shadow Skin to take the rest of the damage until the group finishes off all of the mobs.
Yeah, I did a lot of research on how to play the class properly and just about everything I read said to never use DA+DD or DA+DP while using blood price. Makes perfect sense. But none of them ever explicitly stated that blood price has a set amount of mp restoration regardless of the amount of damage taken. I feel like the guides should suggest popping blood pricee with a defensive CD like shadowskin. I’m sure some of my healers hated me for a while there because I thought that if I had one up, I wasn’t getting all the mp I could have. As it is now, I usually wait until about 3 seconds left on blood price before before popping a DA+DP combo. Generally I try to end a pull or any given fight with at least half mp. I might be wrong, but I feel ffxiv gil like a high level drk that has full mp isn’t capitalizing on their mitigation or damage output.
