Guild Wars 2

I’m thinking of using this build on my warrior purely for dungeons.

Also which stats would you use?
I am thinking of Power/Precision with a mix of toughness/vit on armor and +healing on jewels. And how much toughness/vit/healing should I aim for?

Which Runes would you reccomend. Soldier for my shouts or dps runes?
Also which Sigil would you reccomend?

Any feedback is more then welcome.
Thanks in advance.
