I was just wondering, after update 2.5, what are the best augments for PvE Shadow Tanks. I currently have 69/72/78 level armor and stack all advanced fortitude augments. I have the shield amplification relic, the reactive warding,and 44k hp with 36.44% Defense Rating, 19.91% Defense Chance, 29.13% Shield Chance, and 34.61 Shield Absorption. Which augments should I use to better tank?
