Assuming the below build is one you found, it is for endgame stuff, in granite. I've ran without granite, as build, and it still does fine for most stuff. It's expensive, but psi doesn't matter and run speed in granite is fine. Damage isn't great. But it tanks like no other.
Leveling up, I'd put two-three defense so/io in the shields and one end rudux. Attacks, one acc/dam/end.
Just take taunt. Cause you're a tank. And your job is to tank, so take the taunt power.
