Sith (Health vs. Protection)

I tend to go for protection because at G12 most characters have more protection than health anyways, and a 23.5% boost in protection gives way more survivability than a 5.88% boost to health. I run this same lineup and Vader is the only one I have a CD triangle on, I have a protection triangle on everyone else. I used to run CD on Sion too but now I prefer making him as tanky as possible, extra crit damage doesn't do him too much good if he dies before he gets to Hatred. He still hits like a truck without it and he's even harder to kill.
