Out of curiosity, how does Annihilation improve survivability? The only talents I see that would help with survivability are Hungering (2% health gain on bleed critical), Cloak of Annihilation (retaliate reduces cooldown on cloak of pain), and Subjugation (reduce cooldown on interrupt and obfuscate). I'm guessing the key talent would be Hungering as it gives health on bleed crits and Annihilation will be doing a lot of bleed damage and crits, right? Or is there something else I'm missing?
