Guild Wars 2

Long story short, I am wearing
(Soldier Exotic Gear w/ Soldier Runes)
Power
Vitality
Toughness
I’ve been looking at
(Knight’s Exotic Gear w/ Soldier Runes)
Power
Precision
Toughness
Good change, yes/no..?

And what traits /sigils/weapon combos can I use with them?

First question that comes up is whether you use this build for pve or wvw.
Second question is what weapons do you intend to use.

Regardless, you’re ought to spend points into tactics’ shout traits and grab at least 2 shouts to fully utilize your rune set. Also, since you are spending points in tactics, it is highly useful to grab quick breathing trait and a warhorn for even more condi cleanse, blast, swiftness and other goodies.

Assuming you use this build for wvw, you’d better use knight’s gear with cavalier trinkets, since warrior can sacrifice extra vitality for extra damage. Or go cleric-ish, if all you want to do is to live forever.
