Guild Wars 2

So after looking in the Wiki it seems there are only 3 possible stat combos involving expertise;

Vigilant: major: Power, toughness. Minor: Concentration, expertise

Vipers: major: Power, condition damage. Minor: Precision, expertise

Trailblazers: major: Toughness, Condition damage. Minor: Vitality, expertise

Am I right in saying this is all? I was wanting to try making a Condi Necro of my own (second character that’s just for fun, please no discussion on how its pointless or anything like that) that would be

Major: Condition Damage, Expertise. Minor: Vitality, Precision/Power

Or am I blind/miss informed and there are more available

Correct, those are your only options. Honestly, a necro doesn’t need vitality, generally speaking. We’re pretty darn tanky already, and we have Death Shroud as a second health pool of sorts. If you want a condi necro with Expertise, go with Viper. If you’re truly worried about your ability to survive, you can use trinkets with either Vitality or Toughness.
