skills like Sole Survivor, Dark Arts + [Cooldowns], and Carve and Spit require you to have an intricate understanding of how Tanking in this game works in order to utilize them effectively and efficiently.

I don't know man. I can use DA-CS when burst is needed on say Arcane orb from that Lion boss, but to be honest: most of the time I am mana starved so I just use it for the 800MP.

Sole survivor is a cool skill and imo very easy to use, just mash it on a mob with <10% HP if you need mana.
For what it does it's CD is a bit too long.
