Is Tenacity still a dead stat?

[Zordrage]

I prefer Crit > Ten > Det.

the damage differences are minimal so go with wathever you feel like it.

As a tank i prefer more selfsustain above all else.

Paladins and Warriors got it easy they don't need to care they have crazy good mitigation and Selfsustain.
As a DRK tough i take anything that increases my chances to stay alive.

Heals can Crit and its huge
Ten gives damage reduction AND increase heals
Det also increase heals
