Which Augment for my Tankasin?

[mlambros79]

I am currently in the process of adding Augments slots to my Assasin Tank. Right now I'm grinding the random HM Flashpoints for Black Hole Comms and Columi Gear. My gear is really mixed right now: Columi Head, Black Hole Chest, Tionese Gloves, Legs, Boots, OH, MH then all the "peripherals" are Columi or Black Hole.
In the Aug Slots I was thinking of equipping half Resolve (Willpower/End) and half Fortitude (Endurance/Pwr).
What would be the best Augments to add?
Should I be focusing more on Endurance?

Shield and defense definitely. For me, the war hero gear has a ton of shield already, so I've been boosting defense and willpower because I'm a hybrid dps tank, but that's my PvP main only.

Why do the Shield, Absorb & Defense Augments have Power as the 2nd stat??
Where is Power important for an Assassin Tank?
