If you are unsure about Death Strike not working (ie it doesn't need hit/exp to do what it's supposed to do) like every other tanks form of active mitigation:
Your Death Strike healed You 0 Physical. (40743 Overhealed)
Your Blood Shield refreshed You. (234307 Remaining)
Your Death Strike Dodged Raider's Training Dummy. (Dodged)
To simplify this further, here is a list of abilities that interact with Hit or Both.
Just Hit - Blood Boil, Chains of Ice, Dark Simulacrum, Death and Decay, Death Coil, Icy Touch, Outbreak, Pestilence, Rune Strike
Both - Dancing Rune Weapon, Death Strike (damage only), Heart Strike, Necrotic Strike, Plague Strike, Soul Reaper
A grand total of 0 of those scale with survival for accuracy stats. The only ones you could argue are purely hit based (Outbreak, Blood Boil, Rune Strike) or receive an insignificant amount of use (IT/PS/Harmful Death Coils).
At best you could swap this to Mastery > Hit (to 7.5%) > Avoidance > Haste = Expertise to 15% > Crit.
Keep in mind this is speaking 100% about survival, not the gains of dps in a raid setting, especially that of a tank with how vengeance is.
